Front

What happens to kinetic energy when warm air is put into ice water?

Back

Kinetic energy flows from the air to the ice.

Front

What happens to the temperature of warm air when placed in ice water?

Back

The air gets colder.

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is conduction?

Back

The process of heat transfer through direct contact between materials.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, the kinetic energy of particles increases.

Front

What is thermal equilibrium?

Back

A state where two objects in contact reach the same temperature.

Front

What happens to particles in a substance as it heats up?

Back

They move faster and spread apart.
