answ2. The triple point of water is the temperature at which water may exist in each of its three phases simultaneously. That temperature has been at the 273.16oK defined point for about the last 50 years. Or at 0.16oC.

Answer 2

Water is a gas when it reaches its boiling point of 100 degrees Celsius (212 degrees Fahrenheit) and changes from a liquid to vapor. At this point, water molecules gain enough energy to overcome the intermolecular forces holding them together as a liquid, causing them to escape into the air as water vapor.

Answer 3

Have you ever seen the vapor coming out of the water on a hot stove? That vapor is water in it's gas state.
