You get more used to the heat.
Because turning salt water into fresh water is extremely expensive and eventually we are going to run out of fresh water to drink because the polar ice caps are currently melting!
Evaporation is the proccess of water turning into vapor.
It is common in the water. You can either; Surf or use a Fishing rod (Any). I will be surprised if it took you more then 1 minute for you too find a Magikarp, because they are extremely common.
Water vapor turning into water is a gas changing into a liquid. This process is known as condensation.
At the minute site of the formation of a bubble of boiling, we have some water turning instantaneously to steam. This has a much larger volume than water, and expands VERY rapidly. In this expansion, it forces some water away to make space for the bubble, and it is these forces of expansion, and the reaction to them, that causes the noise.

The amount of water flowing by the gallon per minute affects water pressure in a way that means the higher the volume of water per minute, the higher the pressure the water will be. There is also the factor of air in the pipes that will slow down water pressure significantly.
It mainly depends upon the showerhead. The original generation of showerheads typically dispensed 3.5 to 5.0 gallons per minute (gpm) which would be between 53 and 76 liters in 4 minutes. The first generation of water-saving showerheads dispensed about 2.2 to 2.5 gpm, which would be between 33 and 38 liters in 4 minutes. In the USA, federal law requires new showerheads to have a rate of 2.5 gpm or less. The newest generation of low-flow showerheads use new engineering technology to achieve rates as low as 1.5 gpm, which would be only 23 liters in 4 minutes. You can get the amount even lower by running the water for 1 minute to get wet, turning off the water while soaping up, then turning the water back on for 2 minutes of rinsing; so a 4 minute shower would only use water for 3 minutes, a 25% water savings.

Assuming you mean liquid water turning into gaseous water, that is a physical change, because it's still water (H2O.)
