Thermal Equilibrium and Energy Transfer Review

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other do not exchange heat, meaning they are at the same temperature.

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, and does not require a medium.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, often related to height in a gravitational field.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is a thermal conductor?

Back

A thermal conductor is a material that allows heat to pass through it easily, such as metals.

Front

What is a thermal insulator?

Back

A thermal insulator is a material that resists the flow of heat, such as rubber or still air.

Front

How does heat flow between objects?

Back

Heat flows from an object at a higher temperature to an object at a lower temperature until thermal equilibrium is reached.

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.
