Webb19 apr. 2016 · Why doesn't liquid nitrogen need heat to boil? Be cause its boiling point is very very low and boils at 77.35 K (-195,8 °C) It certainly does require heat, but since its boiling... WebbAbove 212°F at standard pressure, liquid water is unstable. It will evaporate very rapidly from the surface. If the temperature is held constant (which requires some heat input, since evaporation cools things) the liquid will all evaporate. If the temperature is much above 212°F, the water will boil.
