Unit 4 Thermal Energy Test Alternative (ACC)

What is thermal energy?

• The average kinetic energy of a substance

• The total amount of kinetic energy of the molecules in a system

• The measurement of energy in transit between a system with lower kinetic energy and one with higher kinetic energy

What is temperature?

• The measurement of energy in transit between a system with higher kinetic energy and one with lower kinetic energy

• The average kinetic energy of a substance

• The measurement of energy in transit between a system with lower kinetic energy and one with higher kinetic energy

What happens when heat energy moves between a system with higher kinetic energy and one with lower kinetic energy?

• It moves from the system with lower kinetic energy to the one with higher kinetic energy

• It moves from the system with higher kinetic energy to the one with lower kinetic energy

• It stays in the system with lower kinetic energy

What is the impact of differences in temperature on heat transfer between objects?

• Depends on the size of the objects

• No impact

• Faster heat transfer

What causes the sensation that a block of solid aluminum feels cooler than a paperback book even when they are at the same temperature?

• The aluminum block has lower thermal energy

• The aluminum block is a better conductor of heat

• The paperback book is a better conductor of heat
