Water contained in a beaker can be made to boil by passing steam through it Correct Answer At a pressure greater than atmospheric pressure

The boiling point of a liquid is the temperature at which its vapor pressure is equal to the atmospheric pressure. When steam is passed through water, it heats the water, and if the pressure of the steam is greater than the atmospheric pressure, it can make the water boil even at a temperature below 100°C (the boiling point of water at atmospheric pressure).

This phenomenon is utilized in various industrial processes, such as in steam generators and pressure cookers. When steam is supplied at a pressure higher than atmospheric pressure, the water in the beaker can be made to boil even at a temperature higher than 100°C.

Among the options provided, the correct answer is Option B: At a pressure greater than atmospheric pressure. This is because boiling at a pressure higher than atmospheric pressure allows the water to reach its boiling point at a temperature higher than 100°C.

Therefore, the correct answer is Option B: At a pressure greater than atmospheric pressure.
