Thermal Energy Review

Front

What is condensation?

Back

Condensation is the process by which water vapor in the air cools and changes into liquid water, often seen as water droplets on cold surfaces.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

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

Front

How does temperature affect kinetic energy?

Back

Temperature is a measure of the average kinetic energy of particles; higher temperatures mean higher kinetic energy as particles move faster.

Front

What happens to the temperature of a cold drink left outside?

Back

The temperature of the cold drink increases as it absorbs heat from the surrounding air.

Front

What is thermal energy?

Back

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

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred between objects due to a temperature difference, while temperature is a measure of the average kinetic energy of particles.

Front

What is an example of heat transfer by radiation?

Back

An example of heat transfer by radiation is feeling warmth from the sun on your skin.

Front

What is an example of heat transfer by conduction?

Back

An example of heat transfer by conduction is touching a hot stove and feeling the heat transfer to your hand.
