Thermal Energy - 6th

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 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, which can occur in a vacuum.

Front

What happens to particles in a substance as temperature increases?

Back

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

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, the kinetic energy of the particles in 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.

Front

What is an example of convection?

Back

An example of convection is the circular motion of boiling water.
