Mechanical engineer interview questions shared by candidates
What will happen to the boiling point of a liquid under vacuum? Will it rise or decrease?
it will rise because the vapour pressure becomes zero
it should decrease because of very little pressure. Water should boil more easily up in the mountains due to altitude.
It should decrease, because according to the PVT relationship (e.g. PV=nRT), if pressure decreased, the boiling temperature should also be decreased.
