Energy and Temperature

• Gases are made up of molecules that are
  constantly moving. Temperature changes due to
  how active these molecules are.

3
Measuring Temperature

• Temperature is usually measured with a
  thermometer with a liquid of mercury or colored
  alcohol.
• Thermometers work because liquids expand when
  they are hot

How Is Heat Transferred

• Radiation- When you feel heat from the sun, you
  are feeling the energy coming from the sun.
• Conduction- The direct transfer of heat from one
  substance to another substance that it is
  touching.
• Convection- The transfer of heat by the movement
  of fluid.

5
In Daily Life

• Radiation, Conduction, and Convection are in
  your everyday life. For instance you feel
  radiation because when you feel the suns heat on
  your skin that is called radiation.

6
Heat In the Troposphere

• Radiation conduction and convection all work
  together to make the troposphere a suitable
  temperature for life on this planet.
