When air pressure is increased on the surface of water, the temperature required for boiling:?

Question

a) Is raised b) is lowered c) actually does not change

Answer 1

a)is raised.Because in fact if we boil water near the sea surface(1 atm) the water will boil fast(ex.5 mins).but if we boil water at point of a mounthain,far from the sea surface(1.5 atm)the water will boil slowly(ex.10 mins).in daily activity,if we blow a cup of hot coffee(we increase the air pressure on it)it will warm/cool fast right?so air pressure if increase will make something get low temperature.i think it can answer your question.

Answer 2

Think about this logically. Boiling occurs when the force of the water molecules hitting each other reaches a breaking point against the force of air down on it. If you increase that pressure, the water needs to move more, meaning it must be hotter to boil.
