Question:
Cooking is fast in a pressure cooker, because
Cooking is fast in a pressure cooker, because
Show Hint
High Pressure = High Boiling Point = Faster Cooking.
Updated On: Apr 10, 2026
- food particles are effectively smashed
- water boils at higher temperature inside the pressure cooker
- food is cooked at constant volume
- loss of heat due to radiation is minimum
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
The boiling point of a liquid increases with an increase in external pressure.
Step 2: Mechanism
Inside a pressure cooker, the steam is trapped, which significantly increases the internal pressure.
Step 3: Effect
This high pressure raises the boiling point of water above $100^{\circ}C$, allowing the food to cook at a higher temperature.
Step 4: Conclusion
The higher temperature speeds up the chemical and physical changes required for cooking.
Final Answer: (b)
