Question

A beaker of water is placed on a table. It can be made to boil quickly by passing

• A. steam through it by atmosphere pressure
• B. steam through it at a pressure lower than atmospheric
• C. steam through it at a pressure higher than atmospheric
• D. hot water

Answer 1

The correct option is B steam through it at a pressure lower than atmospheric

Steam has higher amount of heat and at low pressure, water boils quickly because it attains equilibrium pressure in less time.

So, a beaker of water is placed on a table. It can be made to boil quickly by passing steam through it at a pressure lower than atmospheric pressure.
