Energy and States of Matter

Kinetic Energy

The energy an object possesses due to its motion, which depends on its mass and velocity.

The faster a particle moves the _______________ kinetic energy it has

more

Temperature

The measure of the average kinetic energy of a substance

Potential Energy

Stored energy due to the interactions between particles or objects.

Highest kinetic and potential energy

Gas

Lowest kinetic energy and potential energy

Solids

Type of matter in the middle with potential and kinetic energy

Liquid

Thermal Energy

The temperature of the particles as well as the distance between those

The ____________ a sample of matter is, the more thermal energy it has.

larger

Atom

Building block of matter

Substance

Matter with a composition that is always the same

Element

Substance that is made up of only one type of atom and cannot be broken down

Compound

A substance made up of two or more different elements chemically joined together

Characteristics of solid particles

Closely packed particles that vibrate in fixed positions, maintaining a definite shape and volume.

Characteristics of liquid particles

Particles that are closely packed but can flow past one another, maintaining a definite volume but not a fixed shape.

Characteristics of gas particles

Particles that are far apart and move freely, filling the available space and not maintaining a definite shape or volume.
