The covered pot will boil first. The concept of equilibrium is sometimes difficult for students to grasp. Place a glass of water on a table top and ask the students whether they think the temperature of the water in the glass is warmer, cooler, or the same as the surroundings. Many will say it is the same. Ask the students whether they think there is any energy flowing into or out of the glass. With some encouragement, they will recognize that the water is slowly evaporating and that this represents energy flow out of the glass.
Will the water just continue to get colder and colder until it freezes? The rate at which heat flows into the glass will depend on the temperature difference between the glass and the surroundings. The water temperature will decrease until energy flowing into the glass balances the loss due to evaporation. Use a lamp with a Watt reflector bulb to help explain the concept of radiation intensity. Ask the student to judge the distance of the bulb. Use the same lamp to illustrate the concepts of reflection, albedo, and absorption by measuring the amount of reflected light from various colored surfaces with a sensitive light meter. The reflectivity of natural surfaces outdoors could be measured or could form the basis for a student or group project. A Watt clear light bulb connected to a dimmer switch can be used to illustrate how the temperature of an object affects the amount and type of radiation that the object will emit. Explain that the passage of electricity through the resistive filament heats the filament.
With the dimmer switch set low, the bulb can be made to glow a dull red. At low temperatures, the bulb emits lowintensity, longwave radiation. As the setting on the dimmer switch is increased, the color of the filament will turn orange, yellow, and then white as increasing amounts of shortwave radiation are emitted. The intensity of the radiation will increase dramatically. Some students have the misconception that a green object reflects all colors but green. Similarly it is important that students understand that a red or green filter transmits red or green light. Put a red and a green or blue filter on an overhead projector and draw a hypothetical filter transmission curve. Put the two filters together and show that no light is transmitted.
Ask the students what happens to the light that is not transmitted by the filter. Why, then, do you feel cold when you step, dripping wet, out of the shower? Discuss the concept of a scale, such as the Celsius scale for temperature. A scale must have a meaningful zero point and a meaningful increment. Discuss the meaning of the zero point for the Celsius scale. Discuss the meaning of a 1° increment of temperature within the Celsius scale. Invite students to comment on the relative merits of the Kelvin, Celsius and Fahrenheit temperature scales. Student Projects 1. Solar irradiance energy per unit time per unit area at the ground can be measured relatively easily. Drill a hole in one side so that a thermometer can be inserted into the middle of the block. Paint one of the two surfaces with flat black paint.
Position the block in a piece of styrofoam insulation so that the painted surface faces outward and is flush with the styrofoam surface. Insert the thermometer into the side of the block. Orient the block so that the black surface is perpendicular to incident radiation from the Sun. Note the time and measure the block temperature every 30 seconds for 10 to 15 minutes. When plotted on a graph, students should find that temperature, T, increases linearly with time, t. The slope of this portion of the graph can be used to infer the solar irradiance, S, using the following equation:. Describe the difference between energy and power.
How is energy related to power? The strength of light bulbs is usually given in watts. Is this energy or power? Explain, using concepts presented in the chapter, why windshield sun shades used in cars are more effective if they are brightly colored. Using the concept of convection, explain why wall heat vents are more effective when they are located close to the floor rather than to the ceiling. Heat is energy in the process of being transferred from one object to another because of the temperature difference between them. a Each degree on the Kelvin scale is exactly the same size as a degree Celsius, and a temperature of 0 K is equal to °C. b Because there are no negative values. Conduction: The transfer of heat from molecule to molecule within a substance. Convection: The transfer of heat by the mass movement in liquids and gases. Radiation: Heat transfer from one object to another without the space between them necessarily being heated. When water vapor condenses into clouds, latent heat is released into the atmosphere.
This provides a tremendous amount of heat in storms, such as thunderstorms and hurricanes. Advection is horizontal; convection is vertical. A small increase in temperature results in a large increase in the amount of radiation emitted because doubling the absolute temperature of an object increases the maximum energy output by a factor of 16, which is The amount of radiation entering the surface of the body equals the amount exiting the surface of the body. Because they absorb and radiate with nearly percent efficiency for their respective temperatures.
The aurora is produced by the solar wind disturbing the magnetosphere. The excited atmospheric gases emit visible radiation, which causes the sky to glow like a neon light. Answers to Questions for Thought 1. New to this edition are Online Appendices that allow students access to a wide variety of supplemental material, including tools for weather prediction and background on watches, warnings, and advisories. On the endsheet at the back of the book is a geophysical map of North America. The map serves as a quick reference for locating states, provinces, and geographical features, such as mountain ranges and large bodies of water.

Radiant Energy Define electromagnetic and radiant energy, and illustrate the relationship between radiation and temperature. Radiation—Absorption, Emission, and Equilibrium Define the terms blackbody, radiative equilibrium temperature, selective absorber, atmospheric window, and describe their relationship to the atmospheric greenhouse effect. Summary This chapter begins with a definition of temperature and a comparison of the absolute Kelvin , Celsius, and Fahrenheit temperature scales. Heat, the flow of energy between objects having different temperatures, occurs in the atmosphere by the processes of conduction, convection, and radiation. Air is a relatively poor conductor of heat but can transport heat efficiently over large distances by the process of convection. The latent heat energy associated with the phase changes of water is shown to also be a very important energy transport mechanism in the atmosphere. A physical explanation of why rising air cools and sinking air warms is given.
The nature of and rules which govern the emission of electromagnetic radiation are reviewed next. Students should find the discussion of Sunburning and UVB radiation in this section interesting and relevant. As the role of greenhouse gases in climate change is undergoing vigorous investigation, the latest research results are presented. Students should understand that the energy Earth absorbs from the Sun consists primarily of short-wave radiation. The energy emitted by Earth is almost entirely in the form of infrared radiation. A useful focus section describes this effect in the context of radiative equilibrium. The final portion of the chapter describes the physical characteristics of the Sun and the causes of the aurora.
Key Terms energy potential energy kinetic energy temperature heat absolute zero Kelvin scale Fahrenheit scale Celsius scale heat capacity specific heat latent heat sensible heat conduction convection thermals. Teaching Suggestions 1. Heat a thin iron bar in a flame from a Bunsen burner or a propane torch. Begin by holding the bar fairly close to the end of the bar. Students will see that heat is quickly conducted through the metal when the instructor is forced to move his or her grip down the bar. Repeat the demonstration with a piece of glass tubing or glass rod.
Glass is a poor conductor and the instructor will be able to comfortably hold the glass just 2 or 3 inches from the tip. Ask the students if they believe energy is being transported away from the hot glass and if so, how? Without heat loss by conduction, the glass will get hotter than the iron bar and the tip should begin to glow red - a good demonstration of energy transport by radiation. Faint convection currents in the air can be made visible if the hot piece of glass is held between an overhead projector and the projection screen. Ask the students what they would do to quickly cool a hot object. Many will suggest blowing on it, an example of forced convection. Someone might suggest plunging the hot object into water. This makes for a satisfying end to the demonstration. Evaporating water can be seen and heard when the hot iron rod is put into the water the glass will shatter if placed in the water. The speed with which the rod is cooled is proof of the large amount of latent heat energy associated with changes of phase.
Ask the students whether they believe water could be brought to a boil most rapidly in a covered or an uncovered pot. The question can be answered experimentally by filling two beakers with equal amounts of water and placing them on a single hot plate to insure that energy is supplied to both at equal rates. It is a good idea to place boiling stones in the beakers to insure gentle boiling. Cover one of the beakers with a piece of foil. The covered pot will boil first. The concept of equilibrium is sometimes difficult for students to grasp. Place a glass of water on a table top and ask the students whether they think the temperature of the water in the glass is warmer, cooler, or the same as the surroundings.

The bridge will become icy first because it is able to lose heat energy over its entire surface; it cools on top, on the sides, and on the underside. The road, on the other hand, loses heat energy quickly, but only at its upper surface. Also, when the road begins to cool, heat may flow up from the warmer ground below. The branches cool rapidly by emitting infrared energy.
