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.

Front

How do particles behave in solids?

Back

Particles in solids are tightly packed and vibrate in place.

Front

What is the difference between conduction and convection?

Back

Conduction is the transfer of heat through direct contact, while convection is the transfer of heat through the movement of fluids.

Front

What happens to the temperature during a phase change?

Back

During a phase change, the temperature remains constant even though heat is being added or removed.

Front

What is evaporation?

Back

Evaporation is the process of a liquid turning into a gas at temperatures below its boiling point.

Front

What is condensation?

Back

Condensation is the process of a gas turning into a liquid when it cools down.

Front

What is radiation in terms of thermal energy transfer?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, which can occur in a vacuum.

Front

What does a horizontal line on a phase change graph indicate?

Back

A horizontal line indicates that there is no change in temperature during a phase change.

Front

What is the boiling point of water?

Back

The boiling point of water is 100 degrees Celsius (212 degrees Fahrenheit) at standard atmospheric pressure.

Front

What is the freezing point of water?

Back

The freezing point of water is 0 degrees Celsius (32 degrees Fahrenheit) at standard atmospheric pressure.
