Thermal Energy

Front

What is thermal energy?

Back

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

Front

What is temperature?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What is conduction?

Back

Conduction is the transfer of energy from one particle of matter to another within an object or between two objects in direct contact.

Front

What is convection?

Back

Convection is a type of heat transfer that occurs through the movement of fluids (liquids or gases).

Front

What is radiation?

Back

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

Front

How does heat transfer occur in cooking?

Back

Heat transfer in cooking can occur through conduction (direct contact), convection (movement of fluids), and radiation (heat from the oven).

Front

What is an example of convection in nature?

Back

An example of convection in nature is water currents that flow from the equator to the poles, moving heat from warmer to colder regions.

Front

What happens to thermal energy when a pizza is cooked in an oven?

Back

The pizza gains thermal energy from the oven, while the oven loses some thermal energy to the surrounding environment.

Front

What is the difference between heat and thermal energy?

Back

Heat is the transfer of thermal energy from one object to another, while thermal energy is the total energy of the particles in an object.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a pot of boiling water.
