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.

What happens to the temperature of water when it boils?

Back

The temperature of water remains constant at 100°C (212°F) at sea level while it is boiling.

Front

What is the process of freezing?

Back

Freezing is the process where a liquid turns into a solid as it loses thermal energy.

Front

How do molecules behave as temperature increases?

Back

As temperature increases, molecules move faster due to increased kinetic energy.

Front

What is the relationship between mass and thermal energy?

Back

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

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

What is the boiling point of water?

Back

The boiling point of water is 100°C (212°F) at sea level.

Front

What is evaporation?

Back

Evaporation is the process where liquid turns into vapor at temperatures below its boiling point.
