Amplify Thermal Energy

Front

What happens when a hot and cold sample first come into contact with each other?

Back

Some of the molecules in both samples will have a different kinetic energy.

Front

How do energy transfers occur between two samples?

Back

Energy transfers occur when they collide with each other.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state reached when two samples have the same temperature and kinetic energy.

Front

What happens to the temperature of two samples after they achieve equilibrium?

Back

The temperature will be the average of the two initial temperatures.

Front

What occurs to the kinetic energy of hot air when it comes into contact with cold air?

Back

The hot air will lose kinetic energy.

Front

What is the definition of thermal energy?

Back

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

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 conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids and gases).

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves.
