Question

Food cooks faster in a pressure cooker since

• A. the pressure exerted by water vapour enclosed in the cooker increases the boiling point of water.
• B. the pressure exerted by water vapour enclosed in the cooker decreases the boiling point of water.
• C. the water vapour pressure does not influence the boiling point of the water.
• D. there is no loss of heat to the surrounding as the pressure cooker is airtight.

Answer 1

The correct option is A the pressure exerted by water vapour enclosed in the cooker increases the boiling point of water.

Food cooks faster in a pressure cooker since, the pressure exerted by water vapor enclosed in the cooker increases the boiling point of water.

pressure $\alpha$ boiling point

Pressure increases, boiling point increases. So food cooks faster.
