There are three states of matter: gas, liquid, and solid. Water in our atmosphere exists in these three states constantly. As the temperature of water vapor (a gas) decreases, it will reach the point at which it turns into a liquid (called the dew point or the point at which dew forms). This change...

Water in its liquid state is visible, as ponds, streams, water in bottles, and wet surfaces. You can also see water in its solid form , ice and snow. Water as a gas in the air, also called water vapor, is invisible. The process of visible liquid water turning into invisible gaseous water is called...

Convection is the density-driven movement of a fluid material. Often, convection is driven by either heating from below or cooling from above the fluid. When a liquid is heated, it expands slightly, which makes it less dense. The fluid with lower density rises up, in the same way that a party...
