matter

​ what happens to matter when it changes states?

matter is anything with mass and takes up space. (solid, liquid and gas)

water changes states because of changes im temperature and pressure.

energy makes molecules vibrate.

the temperature that ice melts is called melting piont. (32 degrees f.)

any extra energy is called heat of fusion.

solid to a gas is called sublimation

the states of matter

gas and liquid are two out of the three main states of matter.

matter is anything that takes up space. (makes up EVERYTHING)

physical matter is composed if atoms

atoms behave differently depending on their environment

water is made of molecules.

liquid molecules are packed together tightly

boiled water is a gas

increasing the heat of water or adding energy leads to molecules moving swiftly and getting farther apart.

if you lower the temperature of water you are taking energy away.

[]

liquid: definite volume and no definite shape

solid: definite volum and definite shape

gas: no def. volume and no def. shape

temperature:the average motion of particles in a substace

atoms: has protons nuetrons and electrons
