Matter

Is anything that has mass and volume. Also all of it are made of small particles

Particles

There are always space between particles—the amount of space varies depending on the state. They are always moving and are attracted to one another

Kinetic molecular theory

It is the energy due to motion.

It explains what happens to matter.

It provides a scientific explanation based off results.

Main points of the kinetic molecular theory

All ?????? is made of very small particles. There is empty space between particles. They are always moving. Energy makes them move—the more energy they have, the faster they move

Liquid can be referred as

Walking

Solid

Can be referred as frozen

Gas can be referred as

Running

Thermal expansion

It is the increase in volume when the temperature is raised

Thermal contraction

Decrease in volume when the temperature is lowered

The difference between heat and temperature

thermal energy is the total kinetic energy of all particles

heat is the transfer of thermal energy between two materials of different temperatures. It is always transferred with a higher temperature to the substance of a lower temperature

Temperatures is the average kinetic energy of the particles ina substance

Mass

The quantity of a matter a substance or object contains. It can be measured in grams or kilograms

Volume

The amount of space taken up by a substance or object. Can be measured by milliliters, lites or cubic centimeters
