Thermal Energy

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object, related to their temperature and movement.

Front

How does temperature affect particle movement?

Back

As temperature increases, particles move faster; as temperature decreases, particles move slower.

Front

What happens to particles when energy is removed?

Back

Removing energy from particles makes them move slower.

Front

What is the state of matter for a gas?

Back

A gas has no definite shape and no definite volume.

Front

Why does ice cream melt?

Back

Ice cream melts because the temperature of its surroundings is warmer than the ice cream.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids and gases).

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, such as sunlight.

Front

What is the relationship between thermal energy and temperature?

Back

Temperature is a measure of the average kinetic energy of particles, while thermal energy is the total energy of all particles.

Front

What happens to the thermal energy of an object when it is heated?

Back

When an object is heated, its thermal energy increases, causing its particles to move faster.
