What is energy?

Back

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

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when particles collide with each other.

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warmer, less dense fluid rises while cooler, denser fluid sinks.

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves. It does not require a medium, so it can occur in a vacuum.

What is a conductor?

Back

A conductor is a material that allows heat or electricity to flow through it easily. Metals like copper and aluminum are good conductors.

Front

What is an insulator?

Back

An insulator is a material that resists the flow of heat or electricity. Examples include rubber, wood, and plastic.

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, causing a change in speed.

What is the difference between heat and temperature?

Back

Heat is the energy transferred between objects due to a temperature difference, while temperature is a measure of the average kinetic energy of particles in a substance.

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
