Question

In a pressure cooker cooking is faster because the increase in vapour pressure :

• A. increase the specific heat
• B. decrease the specific heat
• C. decreases the boiling point
• D. increases the boiling point

Answer 1

Answer:

D. increases the boiling point

This heat is used up by the food to get cooked properly. Thus, in a pressure cooker since the boiling point increases, the steam has greater thermal energy which it can transfer to the food and hence the cooking is faster. Therefore, the correct option is D) increases the boiling point.
