"It is easy to prepare food in pressure cookers". Explain the reason on the basis of the boiling point of water
Answers
Answer:
beacuse it depends up on the fact that increase in external pressure increases the boiling point of liquid.
Explanation:
Liquid boils at a temperature when the vapour pressure of liquid becomes equal to the external pressure. if external pressure is high liquid have to generate more vapours so that vapour pressure becomes equal to external pressure.
In pressure cooker external pressure on the H2O is increased due to which water needs more temperature to boil and generate vapour pressur. As water does not boil at 100 degree remain in liquid form but with more heat so cook the food easily.
Answer:
A liquid boils at a temperature at which it's vapour pressure is equal to the pressure of the gas above it. The lower the pressure of a gas above a liquid, the lower the temperature at which the liquid will boil, so it is easy to prepare food in pressure cooker
