Q. Pressure cooker is fast in cooking rice because

A
it lets the steam escape
B
it does not let the heat energy escape easily
C
high pressure crushes the hard covering of rice grains
D
high pressure raises the boiling point of water
Solution:

Inside a pressure cooker, once the water (liquid) is boiling and the steam is trapped, the pressure from the trapped steam increases and this pushes on the liquid, which increases its boiling temperature, because it becomes harder for the water molecules to escape from the surface as the pressure increases on it.
