Pressure cooker cooks rice faster because
A. it always lets the steam escape
B. high pressure crushes the hard covering of rice grains
C. it does not let the heat energy escape easily
D. high pressure raises the boiling point of water
Answer: Option D
Solution (By Examveda Team)
Pressure cooker cooks rice faster because high pressure raises the boiling point of water. The trapped steam increases the atmospheric pressure inside the cooker by 15 pounds per square inch (psi), or 15 pounds above normal sea-level pressure. At that pressure, the boiling point of water is increased from 212°F to 250°F. This higher temperature is what cooks food faster.This Question Belongs to General Knowledge >> Basic General Knowledge
