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 are solid particles like?

Back

Solid particles are closely packed together and vibrate in place. They have a definite shape and volume.

What is a conductor?

Back

A conductor is a material that allows heat or electricity to pass through it easily. Examples include metals like copper and aluminum.

What is an open system in terms of thermal energy?

Back

An open system is one where matter and energy can enter or leave the system. For example, a cup of hot coffee left uncovered.

Front

What is a closed system in terms of thermal energy?

Back

A closed system is one where matter cannot enter or leave, but energy can be exchanged. For example, a sealed thermos.

Front

Why is it important to change only one variable in an experiment?

Back

Changing only one variable helps to identify what causes the change in the experiment, making results clearer.

What happens to particles in a hot substance?

Back

In a hot substance, particles move faster and are more spread out compared to those in a cooler substance.

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object to another, occurring through conduction, convection, or radiation.

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. For example, a metal spoon getting hot in a pot of soup.
