Thermal Equilibrium

Front

What is thermal equilibrium?

Back

The condition where two substances in physical contact with each other exchange no heat energy, meaning they are at the same temperature.

Front

What is the transfer of thermal energy through space called?

Back

Radiation.

Front

What is the process of heat transfer in boiling water?

Back

Convection.

Front

From where to where does heat always move?

Back

Heat always moves from hot to cold.

Front

If two objects are made of the same types and number of molecules, but one has more thermal energy, how do their molecular speeds compare?

Back

The object with more thermal energy has molecules that move faster.

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 in the form of electromagnetic waves, such as light.

Front

What happens to the temperature of two objects in thermal equilibrium?

Back

Their temperatures become equal.

Front

What is thermal energy?

Back

The total kinetic energy of the particles in a substance.
