Ideal gas equation - PV = nRT
Where, P = Pressure of the gas, V = Volume of the gas, n = Amount of substance, R = ideal gas constant, T = Temperature
- For a constant volume, P ∝ T
Explanation:
- The volume of the cooker is constant
- Due to the increase in temperature, the pressure inside the cooker also increases causing an increase in the boiling point of the water
- In a pressure cooker, the steam formed from the boiling water is not allowed to escape.
- The steam so formed increases the pressure inside the pressure cooker and so the water boils at a higher temperature.
- The time required to cook the food is greatly reduced.
- The water is made to boil at a higher temperature (upto 120°C) than its boiling point (100°C)
