Thermal Energy

Front

What happens to the kinetic energy of air particles when the temperature drops?

Back

The kinetic energy of air particles decreases.

Front

Where can convection currents be found?

Back

Convection currents can be found in gases such as the air.

Front

What is the process called when heat is transferred from particle to particle?

Back

Conduction.

Front

When does heat transfer stop?

Back

Heat transfer stops when the temperature reaches equilibrium.

Front

How is thermal energy transferred between a metal straw and lemonade?

Back

Thermal energy is transferred through conduction.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance.

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 and gases).

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves.

Front

What is equilibrium in terms of thermal energy?

Back

Equilibrium is the state where two objects reach the same temperature and heat transfer stops.
