- 11. Relation between pressure and altitude, temperature and boiling point High pressure, low temperature Low air pressure and high temperature I know that. But... High air pressure, And... We know that ordinary pots are hard to cook on high mountains. Is it because the pressure is low, the boiling point is low? My head is a mess. Sos Also, if the pressure is low, the boiling point is low, then I want to ask, then according to the pressure is low, the temperature is high, the temperature should be high. But the higher the altitude, the lower the temperature
