at what pressure does water boil at room temperature
boiling point is the temperature at which the vapour pressure of a liquid is equal to the atmospheric pressure. so when air pressure is low, it equalises that air pressu â¦ re easily at lower temperatures itself. so its boiling point lowers. Yes. There are two factors that determine a liquids boiling point: temperature and pressure. For water to be boiled at 20oC (room temperature-more or less), it would h â¦ ave to be subjected to about 2.339 kilopascals.
