Thermal Energy

The total amount of energy of all of the particles in a substance.

Heat is energy that is transferred.

Temperature is how we measure the amount of kinetic energy in a substance.

Solids have a definite shape and definite volume.

Liquids have definite volume but not definite shape.

Gases do not have shape or volume.

Energy is always changing form. Just like in solids, liquids and gases.

When this change happens energy is conserved or saved.

So the Law of Conservation of Energy states: Energy cannot be created or destroyed. It only changes to a new form.

Convection: transfer that happens in fluids such as liquids and gases. It is a movement of hot moving up and cool moving down, or circulating in a system.

Conduction: transfer of energy that happens when matter comes in contact with other matter. Like when and ice cube melts in your hand.

Radiation: transfer of energy through electromagnetic waves. This is when you feel heat off of a fire or when you feel the warmth of the sun when you are outside.

Conductors are objects or material that allow energy to transmit or pass through them easily. This would be things like metals and liquids.

Insulators are objects or materials that do not allow energy to pass through to transmit easily. These would be things like wood, glass, plastic, and the fibers that we wear.
