Amplify Thermal Energy C2 Flashcard

Front

What happens to the energy in the molecules of an object when it gets colder?

Back

The energy in the molecules decreases.

Front

How do the molecules of an object behave when it gets colder?

Back

The molecules move slower.

Front

What is the temperature at which two objects at different temperatures will reach thermal equilibrium?

Back

The temperature will be the average of the two, in this case, 50 degrees.

Front

What is absolute zero?

Back

Absolute zero is when molecules have zero molecular movement.

Front

What happens when a hotter object comes into contact with a colder object?

Back

The hotter object will lose energy to the colder object until they reach the same temperature.

Front

What is thermal energy?

Back

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

Front

What is the relationship between temperature and molecular movement?

Back

As temperature increases, molecular movement 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 or gases).

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves.
