Thermal Energy Transfer in Systems

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in a substance, which is related to its temperature.

Front

What is temperature a measure of?

Back

Temperature is a measure of an object's average thermal energy.

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 potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

What is chemical energy?

Back

Chemical energy is a type of potential energy stored in the bonds of chemical compounds.

Front

What does it mean to minimize thermal energy transfer?

Back

To minimize thermal energy transfer means to reduce the flow of heat between objects or systems.

Front

What is a thermos used for?

Back

A thermos is used to keep liquids at a constant temperature by minimizing thermal energy transfer.

Front

What happens when a hot object is placed in cool water?

Back

The thermal energy of the hot object decreases while the thermal energy of the cool water increases until thermal equilibrium is reached.

Front

What is the relationship between thermal energy and temperature?

Back

Thermal energy is related to temperature; as the thermal energy of an object increases, its temperature also increases.

Front

What is an example of thermal energy transfer?

Back

An example of thermal energy transfer is when a hot cup of coffee cools down in a cooler room.
