Question

What do we call the solid form of water? Gaseous form?

Answer 1

Hint: We know that the states of matter are mainly divided into three types and that is, solid, liquid and gas. And each matter has different chemical and physical properties. Water is the only one substance which can exist as solid state, liquid state and vapour state in the earth. In solids, all the particles are arranged very closely. And in the case of liquids, the distance between particles is greater than solid and its shape depends upon the container. The gas does not have any perfect size or shape.

Complete answer:
As we know that pure water is a colorless substance and it does not have any taste and odor. Water is the only one substance which can exist as solid state, liquid state and vapour state on the earth. The solid form of water is known as ice and the gaseous form of water is known as vapour or steam. The solid form of water (ice) is formed by the freezing of water. When the water is freezing, the molecules present in the water will move further apart and the density of ice is less than the water. The volume of water and ice should be the same but the ice will be lighter than the water. That is the reason for the ice floating in water. Water freezes at the temperature of $0^\circ C$. And when the water starts to boil at $100^\circ C$, it is converted into gaseous form which is known as vapour.

Note:
 The particles present in the solid are very far apart. Hence it can move and it has a definite shape and the volume. But the particles present in the gases are spread more easily than liquids and solids. And it can move very fast and freely. Because, the distance between the particles present in the gases is very high and there is no attraction between the gases. Hence, it does not have a perfect volume and shape.
