What is thermal energy that moves from one object to another when the objects are different temperatures.

• temperature

• conduction

• heat

• kinetic energy

Answer explanation

Heat moves from a hotter object to a cooler one. The objects must be different temperatures.

• temperature
• conduction
• heat
• kinetic energy

This state of matter usually expands more.

• liquids

• solids

• gas

This state of matter is better at conducting heat.

• liquids

• solids

• gas

Answer explanation

Because molecules in solids are close together, energy transfers easily between them.

This state of matter is better at insulating.

• liquids

• solids

• gas

Answer explanation

Because gas molecules are more spread out, energy cannot transfer as quickly between them, making them the best insulator.

Heat always transfers from cold to hot.

• true

• false

Answer explanation

Heat always transfers from hot to cold.

States that energy cannot be created nor destroyed, and that it can only change forms.

• conversion of energy

• conservation of energy

• consolidation of energy

• compilation of energy

Friction between two surfaces most often transforms energy of motion directly to:

• electric energy

• thermal energy

• chemical energy

• nuclear energy

Answer explanation

For example, this infrared image shows brakes in a car heating up as they are used to apply friction.

At which point in the diagram shown in Figure A does the box have the most amount of kinetic energy?

• 1

• 2

• 3

• 4

• 5

Answer explanation

This is where the box has the most kinetic energy because it is the point furthest away from the top of the hill.
