When water reaches its boiling point (212oF), its phase changes to gas through the process of evaporation.
During fusion, or the formation of a solid, as in liquid water turning to ice.
The moisture is just water vapor, so you are getting a phase change from liquid to gas. Phase changes are physical changes. For a vaporizer to produce a chemical change it would have to do something drastic like convert the water in to H2 and O2.
the graph would look like a normal heating curve however at 0 degrees celsius and 100 degrees celcius, there would be a flat line.
physical
Evaporation from a pond is not a chemical change. It is a physical change. The water that leaves the pond and goes into the air is not changed from water into some other chemical compound. It's still water, but in the form of a vapor or gas. As the water doesn't chemically change, evaporation is a physical change and not a chemical one.
if the water continued to heat it will become gas
No. It will melt first, then the water in it will boil.
It would be a phase change.
the phase would be solid.
Most parts of the prairie provinces would be under water.
An example of liquid to gas would be water turning to steam without a change in temperature. This is known as vaporization.

Water at -20 degrees Celsius; heat will expand matter, so at +40 degrees Celsius, water would have less density. * * * * * That would be true if there were no phase change. Unfortunately for the above answer, water freezes at 0 deg C and that phase change is accompanied by an expansion. As a result, water at 40 deg C is denser that water (ice) at -20 deg C.
i would assume that sublimation,solid to gas,would be the same answer when going from a gas to a solid.
During a phase change, a substance will remain at a constant temperature while it is being heated. In the case of melting ice, the heat initially goes into separating water molecules from the ice lattice, which is melting. During that time, the heat goes into continued melting of the ice and the temperature remains constant. Once all of the ice is melted, adding additional heat will increase the temperature of the now liquid water.
I believe since the amount of evaporation and condensation in and out of the glass would be equal the amount of water would not change and the temperature would be equal since the enthalpy of the reaction is equal through the phase change. this is just my assumption. ps:are you in ess55 at uci?
