A solid is a state of matter in which the atoms or molecules are tightly packed together and have a fixed shape and volume, a liquid is a state of matter in which the atoms or molecules are close together but can move freely and have a fixed volume but not a fixed shape, and a gas is a state of matter in which the atoms or molecules are far apart and can move freely, with no fixed shape or volume.\n
