Energy Test

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of the particles in an object.

Front

What happens to hot air and cold air?

Back

Hot air rises and cold air sinks due to differences in density.

Front

What energy transformation occurs when a crock pot is turned on?

Back

The transformation is from electrical energy to thermal energy.

Front

What is potential energy?

Back

Potential energy is the energy an object has because of its position or condition, such as a roller coaster at the top of a hill.

Front

What happens to molecules as temperature increases?

Back

As temperature increases, molecules move faster.

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another.

Front

What is an example of electrical energy?

Back

An example of electrical energy is the energy that powers a light bulb.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

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.
