Unit 2 Thermal Energy Post-Test Review

Front

What are the three types of heat transfer?

Back

Conduction, Convection, and Radiation.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids and gases).

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, such as sunlight.

Front

What is thermal insulation?

Back

Thermal insulation is a material that reduces the transfer of heat between objects.

Front

Which material is a good thermal insulator?

Back

Styrofoam is a good thermal insulator.

Front

How does kinetic energy relate to thermal energy?

Back

Kinetic energy is the energy of motion, and it contributes to the thermal energy of an object.

Front

What happens to an object's energy when it heats up?

Back

Energy is transferred to the object, increasing its kinetic energy.

Front

What is the role of temperature in thermal energy transfer?

Back

Temperature measures the average kinetic energy of particles; higher temperatures indicate more energy.

Front

What is an example of conduction in everyday life?

Back

A spoon getting hot when placed in a pot of boiling water.
