If you look up the term "phase diagram," you'll see that, for any given substance, there's a relationship between temperature, pressure, and the state (solid,liquid,gas) that the substance will be in. If you are assuming the piston in your cylinder is immovable, then one thing happens (pressure goes up). If you assume it's movable, then the fluid will ...

Evaporation is simply what happens when a liquid turns into a gas. Liquid that is boiling is very close to the boundary with evaporation. If the system is enclosed (i.e. constant volume and no heat transfer), the pressure must increase. If the system is a piston as you describe, the increase in pressure will push the head out of the cylinder. You are ...

When pure liquid water is left in the open, some of it will evaporate, even if it's not boiling. Evaporated water (vapour) builds up in the atmosphere until an equlibrium is reached between the rate of evaporation (liquid -> vapour) and the rate of condensation (vapour -> liquid). The pressure of water vapour in the atmosphere is known as the 'vapour ...

Water has an interesting property in which on being heated its temperature will not increase beyond its boiling point unless all the water has converted to vapour. This extra energy provided is used in converting water to vapour at the same temperature and is called latent heat of vaporization. So as long as you keep the temperature above the boiling point ...

Water evaporates at all temperatures above freezing point, but weather condenses it back into rain, which finds its way back into the oceans. If atmospheric water was lost into space, at a greater rate than cosmic water entered the Earth's atmosphere, after sufficient undetermined time, all the ocean's waters may be lost.

The boiling point of saturated saline solution is around 108.7°C, so you need a temperature at least as high as this. I wonder if you are mixing up the temperature required with the amount of energy required. As long as we keep the temperature above the boiling point we can evaporate an arbitrarily large amount of water, but of course it will require an ...

Well, I am not at expert and also am new so my answer could be unsatisfying or wrong. But here I go: The temperature should be around 99.97 C for the water to boil. To boil all the water and evaporate the water in all the oceans, the same temperature of 99.97 C could work if the equal amount of heat is applied to all the molecules. That is, if each molecule ...
