Thermal Energy Unit Review

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 happens to particles when temperature increases?

Back

When temperature increases, the kinetic energy of the particles increases, causing them to move faster.

Front

What is the relationship between temperature and kinetic energy?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another due to a temperature difference.

Front

What direction does heat flow?

Back

Heat flows from an area of higher temperature to an area of lower temperature.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light.

Front

What is surface area and how does it affect heat transfer?

Back

Surface area is the total area of the surface of an object. A larger surface area allows for more heat transfer.

Front

What is the effect of ice cube size on melting rate?

Back

Smaller ice cubes have a larger surface area compared to larger cubes, leading to a faster melting rate.
