MCQ
A person living in Shimla observed that cooking food without using pressure cooker takes more time. The reason for this observation is that at high altitude :
  • A
    Pressure increases.
  • B
    Temperature decreases.
  • ✓
    Pressure decreases.
  • D
    Pressure decreases.

Correct option: C.
Pressure decreases.
At high altitudes, pressure is low. Hence, boiling takes place at lower temperature and therefore, cooking takes more time. In pressure cooker, pressure is high and hence boiling point increases.
