Final Test Thermal Energy Amplify

Front

An iron transfers heat to clothing through ___________.

Back

Conduction

Front

Which sample has molecules with more average kinetic energy?

Back

Sample A because it has faster moving molecules.

Front

The average kinetic energy of the molecules that make up this sample is __________.

Back

3

Front

When will the heat transfer stop between two samples?

Back

Heat transfer will stop when sample A and sample B have reached the same temperature.

Front

If a cup of hot chocolate is put in the microwave, would that add or remove thermal energy to the hot chocolate?

Back

Thermal Energy is Added.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light.

Front

What happens to the kinetic energy of molecules as temperature increases?

Back

The average kinetic energy of the molecules increases.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact no longer transfer heat, as they have reached the same temperature.
