Is the temperature of water only related to pressure?
Of course not; it is also related to the levels of other components in the water!
I’m not quite clear about the purpose of your question: For example, in water in a pond, the relationship between water temperature and pressure is not significant; when the pressure remains constant, the water temperature depends on the ambient temperature. Of course, if we heat the water, then its temperature is no longer closely related to the ambient temperature, and it can be adjusted to any temperature below the boiling point but above the ambient temperature (at atmospheric pressure)
The original poster is wondering: Is the boiling point only related to pressure?
You must be asking about the boiling point of water, right?
Factors that affect boiling point include the air pressure at the surface of the liquid and the purity of the liquid
I understand what you mean. The saturated vapor pressure of water is a function of temperature alone; in other words, there is a one-to-one relationship between the saturated vapor pressure of water and temperature. When water boils at 100 degrees, it means that the atmospheric pressure at that location is 101.3 kPa, which is the standard atmospheric pressure. On the plateau, water boils at 90 degrees, which indicates that the atmospheric pressure here is 70.11 kPa.
For pure water, the temperature of saturated steam corresponds to a specific pressure; whereas for superheated steam, one pressure can correspond to multiple temperatures 【of course, within the range of critical temperature and pressure】, and this is related to the dryness of the steam. If it is not pure water, then the vapor pressure depends not only on temperature but also on the components of the solution.
Probably not, but pressure can affect the boiling point of water
I seem to have read in articles before that, in addition to pressure and purity, the degree of hydrogen bonding in water also has an impact; external fields can also bring about changes
