Investigation 4

Question 1

Heat

Answer 1

Measure of the average kinetic energy

Question 2

Radiation

Answer 2

The transfer of energy without direct contact (e.x. the sun)

Question 3

Differential Heating

Answer 3

When different materials heat up at different rates

Question 4

Conduction

Answer 4

Molecules transfer heat by contact

Question 5

Kinetic Energy

Answer 5

Energy of motion

Question 6

How the Atmosphere is Heated

Answer 6

• sun uses radiation to heat the atmosphere
• air molecules use conduction to heat the ground
• the surface then heats more of the ground using conduction
• the ground uses re-radiation to heat Co2 and H2o vapor in the air
• Co2 and H2o use conduction to heat N2 and O2
• N2 and O2 heats the atmosphere
