OpenSciEd 6.2: Thermal Energy

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. It is related to temperature and heat.

What is a closed system?

Back

A closed system is a physical system that does not allow matter to enter or leave, but can exchange energy with its surroundings.

Front

What happens to thermal energy when you heat a substance?

Back

When you heat a substance, thermal energy is added, causing the particles to move faster and increasing the temperature.

What are liquid particles like?

Back

Liquid particles are close together but can move past each other, allowing liquids to take the shape of their container.

What are gas particles like?

Back

Gas particles are far apart and move freely, filling the entire volume of their container.

Front

What is conduction?

Back

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