Question

A pressure cooker raises the internal pressure to about 1.5–2 atm. What is the approximate boiling point of water inside it?

Options

• 100°C

• 80°C

• 105°C

• 120°C

Answer 1

120°C

Explanation:

At 1.5–2 atm pressure, water boils at about 120°C instead of 100°C, so the higher temperature cooks food faster.
