Unit Test: Energy

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact of particles. It occurs when heat moves from a hotter object to a cooler one through physical touch.

Front

What type of energy is stored in an object due to its position?

Back

Potential energy is the energy stored in an object due to its position or condition.

Front

What is an insulator?

Back

An insulator is a material that does not allow heat to pass through it easily, such as rubber or glass.

Front

How does heat transfer between areas of different temperatures?

Back

Heat transfers from an area of high temperature to an area of low temperature.

Front

Which of the following is an example of chemical energy?

Back

A battery is an example of chemical energy, as it stores energy in chemical form.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, depending on its mass and speed.

Front

What is the difference between potential and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is the energy of motion.

Front

What happens to heat energy when it is transferred?

Back

When heat energy is transferred, it moves from a warmer object to a cooler object until thermal equilibrium is reached.
