Answer:

It is due to the density of the water

Explanation:

When we lower down the pressure the water molecules get separated and due to which it takes a more time to boil. Thus water boils slowly in low pressure.

Hope this will help you

thegodtroyna: When the molecules are far apart shouldn't it take less time to change the water into vapour.

suyashprakash03: no

thegodtroyna: Why

suyashprakash03: molecules are far but water is still in liquid condition

thegodtroyna: Ok thanks

suyashprakash03: and all molecules are together in the container as water

suyashprakash03: you can easily change ice into vapour as compared to liquid on boiling

Explanation:

Water boils faster as the Pressure is reduced.

Keeping the temperature constant if you keep a vessel inside a bell jar connected to a vacuum pump , it is absolute magic to see the water start boiling ,at room temperature,without application of any heat, as the bell jar is evacuated .

If the pressure is increased the water starts boiling at higher temperature ,for example in a pressure cooker, so the food gets cooked faster or difficult food products which take hours to cook at normal pressure get cooked in minutes.
