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

"High pressure, low temperature
Low air pressure, high temperature." This must be at the same level (i.e. at the same altitude).
"High pressure, high altitude?" The higher the altitude, the lower the pressure, not the higher.
"It's hard to cook rice in an ordinary pot on a high mountain.
Is it because the pressure is low and the boiling point is low?" That's right. High mountains have low air pressure, low boiling point of water and uncooked rice.
"Also, if the air pressure is low, the boiling point is low, then I want to ask, then according to the air pressure is low, the temperature is high, the temperature should be high ah. But the altitude is high, the temperature is not the altitude higher, the temperature is lower?". Do not understand your question. Many conclusions can not be confused, must be in a certain condition to be true. If there is a problem, you can leave a message to me, the specific answer to you.

The boiling point of all liquids increases with atmospheric pressure, doesn't it

Sorry, I was wrong.
Boiling point increases with atmospheric pressure, gravity reason
