Chemical changes, or reactions, result in the formation of new substances when bonds are. formed and/or broken. Some relatively simple but common types of chemical reactions are. illustrated in this experiment. Examples and descriptions of each type appear below.
Water boils when it reaches 212 degrees Fahrenheit. Water at a high altitude (for example, in a town in the mountains) doesnât have to get as hot in order to boil. In fact, water doesnât have to boil in order to turn from a liquid to a gas! For example, water at the surface of a lake can evaporate, or change to water vapor when heated by the sun!

Water boils to make the pressure in the bubbles that are formed by the application of heat equalize with the atmospheric pressure. Water makes this happen at its boiling point. This boiling point of water differs based on the height at which the water must vaporize.ater boils to change its liquid state to a gaseous state, which is called water vapor. When water changes from a liquid form to a vapor form it takes up some energy. This energy is called the latent heat of evaporation.
