There are four states of matter with certain elements especially water. These include solids, liquids, gas and plasma. Most of these are common except plasma. People have heard of solids, liquids and gases. When you think of water, it can be frozen into a solid where the particles are somewhat close together and still. Liquid particles as water is in its natural form moves around.
Water as gas is seen in water vapor and the particles move around freely. For both the liquid and gas, these particles are close together. Plasma is defined as a type of gas but the particles are very far apart compared to the other three states of matter. Plasma can be seen in neon signs.
