Heat and Temperature Review

Front

What is entropy?

Back

Entropy is a measure of disorder in a system.

Front

How can energy be transferred from a cool object to a warm object?

Back

Work must be done to transfer energy from a cool object to a warm object.

Front

When heat flows, which direction does it move?

Back

Heat flows from a warmer object to a cooler object.

Front

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

Back

The kinetic energy of molecules increases as temperature increases.

Front

How does heat move to melt ice?

Back

Heat moves from the water to the ice to melt it.

Front

What is the relationship between heat and temperature?

Back

Heat is the energy transferred due to temperature differences, while temperature is a measure of the average kinetic energy of particles.

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 through electromagnetic waves, without the need for a medium.

Front

What is thermal equilibrium?

Back

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