Thermal Energy

Front

What is thermal energy?

Back

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

Front

What is a conductor?

Back

A conductor is a material that allows heat to flow through it easily, such as metals.

Front

What is an insulator?

Back

An insulator is a material that resists the flow of heat, such as wood or rubber.

Front

What is convection?

Back

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

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is radiation?

Back

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

Front

How does heat transfer occur between two objects?

Back

Heat transfers from the hottest object to the coolest object until thermal equilibrium is reached.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact no longer transfer heat to each other because they are at the same temperature.

Front

What are some examples of good conductors of heat?

Back

Examples of good conductors include metals like copper, aluminum, and silver.

Front

What are some examples of good insulators?

Back

Examples of good insulators include wood, rubber, and plastic.
