Amplify Thermal Energy Review

Front

What is thermal energy?

Back

The total energy of all the particles of an object measured with temperature.

Front

What happens when two objects with different temperatures touch?

Back

Heat transfer occurs from the hotter object to the cooler object.

Front

What is the role of temperature in heat transfer?

Back

Temperature determines the direction of heat transfer; heat flows from higher to lower temperature.

Front

What is thermal equilibrium?

Back

A state where two objects in contact reach the same temperature and no heat transfer occurs.

Front

How does energy transfer occur when cooking on a grill?

Back

The grill molecules transfer energy to the food, causing it to heat up.

Front

True or False: A higher temperature always means longer heat retention.

Back

False; heat retention depends on the material and its specific heat capacity.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is convection?

Back

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

Front

What is radiation?

Back

The transfer of heat through electromagnetic waves without the need for a medium.

Front

What is specific heat capacity?

Back

The amount of heat required to raise the temperature of 1 kg of a substance by 1°C.
