The range of normal residential water pressure is from 30 to 80 psi. Ideally, the pressure should be set between 45 and 60 pounds in most residential Plumbing systems.If the pressure rises too high particularly above 80 psi, Plumbing fixtures and appliances (primarily water heaters) could be damaged or leak excessively.
Pure water, at normal pressure will freeze.
There is no such thing as normal water pressure, it is changing all the time due to demand in the water distribution system. If a PRV is needed then the pressure is higher upstream than is wanted.
100c
Water boils at 100 degrees Celsius under normal atmospheric pressure.
Water is a liquid at room temperature and normal pressure.
At the standard atmospheric pressure of 101325 Pa water boils exact at 100 degrees Celsius.
The pressure at the normal boiling point of water is 1 atmosphere, which is equivalent to 101.3 kilopascals or 760 millimeters of mercury. At this pressure, water boils at 100 degrees Celsius (212 degrees Fahrenheit).
It depends on the pressure. At normal atmospheric pressure, the melting point of water is about 273.15 K.
80 psi or less
yes
1 atm
It depends of the pressure, but at normal pressure, 1.01325 Pa, the water freezes at 0°C.
