The cold war is the political and military tension between democracy and communism. This happened between the United States and the soviet Union. its called the cold war because no weapons were fired.

Just like any substance, water can exist in three different forms, called states: solid, liquid and gas. The state will change when the substance is heated. As a solid, a substance has a fixed volume and shape and is usually unable to flow, except in the case of glaciers. For instance, an ice cube or snowflake is the solid state of water. When a solid is heated, it turns into a liquid. As a liquid, a substance has a fixed volume, but its shape changes to fill the shape of its container. For instance, a glass of water is the liquid state of water. When a liquid is heated, it turns into a gas. As a gas, a substance does not have a fixed volume or shape.
