OpenSciEd 6.2: Thermal Energy

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of the particles in an object.

What happens to the particles in matter when it is heated?

Back

When matter is heated, its particles move faster and spread apart, increasing the thermal energy.

What is the difference between an open system and a closed system?

Back

An open system allows matter and energy to enter and leave, while a closed system does not allow matter to enter or leave, but can exchange energy.

Front

What is conduction?

Back

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

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids and gases) caused by differences in temperature.

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as heat from the sun.

Front

What is a conductor?

Back

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

What is the state of matter for water?

Back

Water is a liquid state of matter, where particles are close but can move past each other.
