Ability to do work

Matter is not created nor destroyed in any chemical or physical change

Stored Energy

Energy of motion

Kinetic or potential energy associated with the motion or position of an object

produced by electrically charged particles

Energy caused by an object's vibrations

Energy stored in chemical bonds

Heat energy

energy of electric charges

Energy stored in the nucleus of an atom

energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space

energy can transfer from one form to another (e.g. nuclear to heat, chemical to mechanical, electrical to light )

measure of the average kinetic energy of the molecules in a material

Form of heat transfer where heat energy is directly transferred between molecules through molecular collisions or direct contact.

Process by which, in a fluid being heated, the warmer part of the mass will rise and the cooler portions will sink.

Energy that is radiated or transmitted in the form of rays or waves or particles.

A material that does not allow heat or electrons to move through it easily.

the movement of energy from a warmer object to a cooler object

gas molecules have the greatest degree of motion. liquid molecules have more freedom of movement than those in a solid.

a change from one state (solid or liquid or gas) to another without a change in chemical composition

a material system in which mass or energy can be lost to or gained from the environment.

a physical system that doesn't exchange any matter with its surroundings, and isn't subject to any force whose source is external to the system.

the heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree)

the transfer of physical energy from one body or place to another.
