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 an object.

What happens to particles in a solid?

Back

In a solid, particles are closely packed together and vibrate in place.

Front

What happens to particles in a liquid?

Back

In a liquid, particles are close together but can slide past one another, allowing liquids to flow.

Front

What happens to particles in a gas?

Back

In a gas, particles are far apart and move freely, filling the space available.

Front

What is heat?

Back

Heat is the transfer of thermal energy from one object to another due to a temperature difference.

Front

What is specific heat?

Back

Specific heat is the amount of heat required to raise the temperature of 1 kilogram of a substance by 1 degree Celsius.

Front

How does increasing the mass of ice affect thermal energy transfer?

Back

Increasing the mass of ice requires more thermal energy to melt, demonstrating the relationship between mass and energy.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids and gases).
