1 / 14

Which will be hotter if left in the sun?
1. A dark colored car
2. A light color car
"Heat does not rise; hot air rises." Which of the following proves that heat does not rise?
1. You put your hand on a hot object and your hands gets hot.
2. Steam burns your hand over a boiling pot of water.
3. An upstairs room is warmer than a downstairs room.
4. You put your hand under a heat lamp and still feel the heat.
These materials transfer heat quickly (allowing heat transfer).
1. Insulators
2. Conductors
Which absorbs more radiant energy?
1. Light objects
2. Dark objects
Which of the following shows the correct heat transfer?
Why does hot air rise?
1. Hot air is less dense that cool air. Less dense objects "float" or rise up.
2. Hotter air has more thermal energy which allows the molecules to bounce up higher.
3. Hot air molecules have more thermal force to resist gravity.
How does heat transfer between objects?
1. Heat transfers from cold to hot.
2. Heat transfers by electromagnetic waves that don't care about direction.
3. Heat transfers from hot to cold.
When two objects are at the same temperature we say they are at:
1. Insulation state
2. Thermal equilibrium
3. Thermal nirvana
4. State of heat equality
Which of the following is correct?
Which one will be cooler if left in the sun?
1. A shiny object
2. A dull object
Which of the following is not at thermal equilibrium?
What absorbs more radiant energy?
1. Shiny objects
2. Dull objects
These materials transfer heat slowly (resist heat transfer).
1. Insulators
2. Conductors
Which of the following is at thermal equilibrium?
