Thermal Energy

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 particles in an object.

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Hot fluid rises while cooler fluid sinks, creating a cycle.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. Heat moves from the hotter object to the cooler one.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light. It does not require a medium to travel.

Front

What is an insulator?

Back

An insulator is a material that does not conduct heat well, preventing heat transfer. Examples include rubber, glass, and cloth.

Front

What is a conductor?

Back

A conductor is a material that allows heat to pass through it easily. Examples include metals like copper and aluminum.

Front

What happens to air when it is heated?

Back

When air is heated, it expands, becomes less dense, and rises.

Front

What is thermal clothing?

Back

Thermal clothing is designed to retain body heat, keeping the wearer warm in cold conditions.

Front

How does heat transfer from hot tea to a metal spoon?

Back

Heat transfers from the hot tea to the metal spoon by conduction.

Front

Why do we use oven mitts?

Back

Oven mitts are used because they are insulators that protect our hands from heat when handling hot objects.
