Thermal Energy, Temperature and Heat

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object due to their motion and position.

Front

What is temperature?

Back

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

Front

What is heat?

Back

Heat is the transfer of thermal energy from a warmer object to a cooler object.

Front

What happens to particles when they are heated?

Back

When particles are heated, they gain energy and move faster.

Front

What is absolute zero?

Back

Absolute zero is the lowest possible temperature, where all particle motion stops, equivalent to -273.15°C or 0 Kelvin.

Front

How does heat transfer occur?

Back

Heat transfer occurs only from warm objects to colder ones.

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
