CONCEPT:

• The pressure cooker is based on the principle that the boiling of water increases with the increase in pressure.

EXPLANATION:

• When we give heat to the pressure cooker then due to an increase in temperature the steam generated in the vessel.
• Due to this generated steam, the pressure inside the vessel increases. So the food gets cooked soon.
• Thus by the application of pressure the boiling point of the water increases. Hence option 1 is correct.
• There is no relation between food-grains with the boiling point of water. So options 2, 3, and 4 are wrong.
