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

Do molecules move at the same speed no matter what the temperature?

Back

False.

Front

When will there always be heat transfer between two objects that are touching?

Back

There is a difference in temperature between samples.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion.

Front

From where to where does energy transfer occur?

Back

Energy will always be transferred from the hotter sample to the colder sample.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of all the particles in an object.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, the average kinetic energy of the molecules increases.

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 through electromagnetic waves.
