Question

In a pressure cooker, food cooks faster mainly because:

Options

• There is no boiling inside the cooker

• Water boils at a higher temperature, around 120°C

• Water boils at a lower temperature inside

• Water boils at 100°C inside the cooker

Answer 1

Water boils at a higher temperature, around 120°C

Explanation:

In a pressure cooker, trapped steam increases pressure, raising the water’s boiling point above 100°C, so food cooks faster at the higher temperature.
