Question

Why does food cook faster in a pressure cooker?

Options

• It lowers the boiling point of water

• It increases pressure, raising the water’s boiling point

• It removes all the air inside

• It heats food only by radiation

Answer 1

It increases pressure, raising the water’s boiling point

Explanation:

In a pressure cooker, increased pressure raises the boiling point above 100 °C, so food cooks faster at a higher temperature.
