Thermal Energy - Unit 5, Week 2

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 the principle of heat transfer?

Back

Heat always moves from hot to cold.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the movement that transfers heat in a fluid (liquid or gas) through currents.

Front

What is radiation?

Back

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

Front

What is temperature?

Back

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

Front

What is a conductor?

Back

A conductor is a material that allows heat to pass through it easily, such as metals.

Front

What is an insulator?

Back

An insulator is a material that does not allow heat to pass through it easily, such as wool or rubber.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact no longer transfer heat to each other, as they are at the same temperature.

Front

What is specific heat?

Back

Specific heat is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.
