Thermal Energy - Unit 5, Week 2

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 conduction?

Back

Conduction is the transfer of heat through direct contact of particles in a solid.

Front

What is convection?

Back

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

Front

What is radiation?

Back

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

Front

What is thermal equilibrium?

Back

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

Front

How does heat transfer occur in solids?

Back

Heat transfer in solids occurs primarily through conduction.

Front

How does heat transfer occur in liquids and gases?

Back

Heat transfer in liquids and gases occurs primarily through convection.

Front

What happens to particles in a gas when it is heated?

Back

When a gas is heated, its particles move faster and spread apart, increasing the gas's thermal energy.

Front

What is the relationship between temperature and thermal energy?

Back

As temperature increases, the thermal energy of a substance also increases.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a hot soup.
