2-Thermal Energy

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object due to their motion and position. It is related to temperature and heat.

Front

How does thermal energy transfer occur?

Back

Thermal energy transfers through conduction, convection, and radiation.

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) caused by differences in temperature.

Front

What is radiation?

Back

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

Front

What happens to thermal energy when two objects at different temperatures touch?

Back

Thermal energy will transfer from the hotter object to the cooler object until they reach the same temperature.

Front

What is the relationship between temperature and thermal energy?

Back

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

Front

What is the principle of conservation of energy?

Back

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

Front

What is an example of thermal energy transfer in everyday life?

Back

An example is when you touch a hot stove and heat transfers from the stove to your hand.

Front

What is the effect of mass on thermal energy?

Back

Objects with more mass generally have more thermal energy because they contain more particles.
