States of matter

Solid

a state of matter that has a definite shape and volume because the bonds between the molecules or atoms within the structure are strong

Liquid

a state of matter that has a definite volume but an undefined shape because there are weak bonds between the molecules or atoms within the substance

Gas

a state of matter that has an indefinite volume and shape because there are usually no bonds between the molecules or atoms within the substance

Melting
