Thermal Energy

Front

What form of energy causes water to boil?

Back

Thermal energy is the form of energy that causes water to boil.

Front

Which ice cube will melt first?

Back

The small cube will melt first because it has a larger surface area relative to its volume, allowing it to absorb heat more quickly.

Front

What is the energy of motion called?

Back

Kinetic energy is the energy of motion.

Front

What is the process of heat transfer through direct contact called?

Back

Conduction is the process of heat transfer through direct contact.

Front

What is the process of heat transfer in boiling water?

Back

Convection is the process of heat transfer in boiling water.

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 conduction and convection?

Back

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

Front

What is radiation in terms of heat transfer?

Back

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

Front

How does the size of an ice cube affect its melting rate?

Back

Smaller ice cubes melt faster than larger ones due to a higher surface area to volume ratio.

Front

What happens to the thermal energy of water when it freezes?

Back

When water freezes, its thermal energy decreases as the molecules lose energy and form a solid structure.
