Water boils at `120^@`C in a pressure cooker. Explain the reason.

When water is boiled at 2 atm pressure the latent heat of vaporization is 2.2xx10^(6) J//kg and the boiling point is 120^(@)C At 2 atm pressure 1 kg of water has a volume of 10^(-3)m^(-3) and 1 kg of steam has volume of 0.824m^(3) . The increase in internal energy of 1 kg of water when it is converted into steam at 2 atm pressure and 120^(@)C is [ 1 atm pressure =1.013xx10^(5)N//m^(2) ]

explain why cooking is faster in a pressure cooker.

Assertion (A): Water boiling at 100^(@)C at 1 atmospheric pressure in a beaker is not at equilibrium. Reason (R ): If refers to an open system.

Rishi is surprised when he sees water boiling at 115^(@)C in a container. Give reasons as to why water can boil at the above temperature.

Steam is present in a pressure cooker at 1.5 atm pressure and 150^(@)C . If the pressure cooker can withstand a maximum of 4 atm pressure and there is no provision of a weight atop the cooker then at what temperature will the cooker explode?

A pressure cooker reduces cooking time because

Assertion (A): Cooking time in pressure cooker is reduced. Reason (R ): The boiling point inside the pressure cooker is raised.
