Question

A pressure cooker is based on the principle that boiling point of water increases with the_______.

• A. Increase in temperature
• B. Increase in volume
• C. Increase in pressure
• D. Decrease in pressure

Answer 1

The correct option is C

Increase in pressure

The pressure cooker is based on the principle that the boiling point of water increases with the increase in the pressure. Food can be cooked faster in a pressure cooker since the boiling point of water increases with pressure. The pressure cooker consists of a pressurized pot which has controlled vent at a specified pressure above atmospheric pressure. It raises the boiling point to about 121${}^{0}C$ or 257 ${}^{0}F$.
