Thermal Energy

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of the particles in an object.

Front

What are the three methods of heat transfer?

Back

Conduction, Convection, and Radiation.

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).

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light.

Front

What happens to thermal energy when ice melts?

Back

When ice melts, thermal energy is absorbed from the surroundings, causing the ice to change from solid to liquid.

Front

Why does a small ice cube melt faster than a large one?

Back

A small ice cube has a larger surface area relative to its volume, allowing it to absorb heat more quickly.

Front

Can thermal energy be transferred from cold to hot objects?

Back

No, thermal energy naturally flows from warmer objects to colder ones.

Front

What is an example of conduction in everyday life?

Back

An example of conduction is when a metal spoon gets hot after being placed in a hot pot of soup.

Front

What is an example of convection in everyday life?

Back

An example of convection is the way warm air rises and cool air sinks in a room.
