Thermodynamics Quiz

How does heat transfer between objects?
1. Heat transfers from hot to cold.
2. Heat transfers from cold to hot.
3. Heat transfers by electromagnetic waves that don't care about direction.
Which of the following shows the correct heat transfer?
Which of the following is correct?
These materials transfer heat slowly (resist heat transfer).
1. Insulators
2. Conductors
These materials transfer heat quickly (allowing heat transfer).
1. Insulators
2. Conductors
When two objects are at the same temperature we say they are at:
1. Thermal equilibrium
2. Thermal nirvana
3. Insulation state
4. State of heat equality
Which of the following is at thermal equilibrium?
Which of the following is not at thermal equilibrium?
"Heat does not rise; hot air rises." Which of the following proves that heat does not rise?
1. You put your hand under a heat lamp and still feel the heat.
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 on a hot object and your hands gets hot.
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.
What absorbs more radiant energy?
1. Shiny objects
2. Dull objects
Which absorbs more radiant energy?
1. Dark objects
2. Light objects
Which will be hotter if left in the sun?
1. A dark colored car
2. A light color car
Which one will be cooler if left in the sun?
1. A shiny object
2. A dull object
