Thermal Equilibrium

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two or more objects in thermal contact no longer exchange heat, meaning they are at the same temperature.

Front

At what temperature does heat stop moving between two objects?

Back

Heat stops moving when both objects reach the same temperature.

Front

What type of heat transfer occurs in solids?

Back

Conduction.

Front

What is conduction?

Back

Conduction is the transfer of heat through a solid material without any movement of the material itself.

Front

What is convection?

Back

Convection is the transfer of heat through fluids (liquids and gases) caused by the movement of the fluid itself.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, which can occur in a vacuum.

Front

What is the formula for calculating heat transfer?

Back

Q = mcΔT, where Q is the heat transferred, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature.

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of one kilogram of a substance by one degree Celsius.

Front

What happens to the temperature of an object when it absorbs heat?

Back

The temperature of the object increases.

Front

What happens to the temperature of an object when it loses heat?

Back

The temperature of the object decreases.
