Thermal Energy and Heat Transfer

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of all the particles in an object, which is related to its temperature.

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another.

Front

What are the three methods of heat transfer?

Back

The three methods of heat transfer are conduction, convection, and radiation.

Front

What is conduction?

Back

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

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 radiation?

Back

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

Front

How does thermal energy affect particle movement?

Back

As thermal energy increases, the movement of particles increases, leading to higher temperatures.

Front

What happens to thermal energy when an object cools down?

Back

When an object cools down, thermal energy is transferred from the object to its surroundings.

Front

What is the freezing point?

Back

The freezing point is the temperature at which a liquid turns into a solid.

Front

Does an object have kinetic energy at the freezing point?

Back

No, at the freezing point, the particles have minimal kinetic energy.
