U2C6L3 Heat energy on the move /Thermal energy/Temperature

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

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 the difference between temperature and thermal energy?

Back

Temperature is a measure of the average kinetic energy of particles in a substance, while thermal energy is the total energy of all the particles.

Front

What happens to the temperature of water when heat is added?

Back

The temperature of the water increases as heat is added, and it may eventually change state from liquid to gas.

Front

What is the normal room temperature range in Celsius?

Back

The normal room temperature range is 20 to 30 °C.

Front

What is the normal room temperature range in Fahrenheit?

Back

The normal room temperature range is 68 to 85 °F.

Front

What is the process of heat transfer from a hot object to a cooler one called?

Back

This process is called conduction, convection, or radiation, depending on the method of transfer.

Front

What is an example of conduction?

Back

An example of conduction is when a metal spoon becomes hot after being placed in a pot of hot soup.

Front

What is an example of convection?

Back

An example of convection is the movement of warm air rising and cool air sinking in a room.

Front

What is an example of radiation?

Back

An example of radiation is the heat from the sun warming your skin.
