What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, such as thermal, mechanical, electrical, and chemical.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the energy that causes the particles in a substance to move.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object. It is the energy associated with the motion and position of an object.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It is used to power devices like toasters and light bulbs.

Front

What is evaporation?

Back

Evaporation is the process by which liquid water turns into water vapor (gas) due to the addition of thermal energy.

Front

What is the role of heat in changing states of matter?

Back

Heat can cause matter to change its state, such as melting a solid into a liquid or boiling a liquid into a gas.

Front

What is an example of energy transformation?

Back

When a toaster is used, electrical energy is transformed into thermal energy to toast the bread.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a stretched rubber band has potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion. The faster an object moves, the more kinetic energy it has.

Front

What is the difference between thermal energy and temperature?

Back

Thermal energy is the total energy of all the particles in a substance, while temperature is a measure of the average energy of those particles.
