Question

Why does water boil at a higher temperature inside a pressure cooker, where the pressure is greater than 1 atm?

Answer 1

due to the pressure because when we add impurity to water it boils at lower temperature as compared to pure water due to elevation of boiling point

Answer 2

For water, the vapour pressure reaches the standard atmospheric pressure of 1 atmosphere at 100°C. So the normal boiling point of water is 100°C (212°F or 373K).The boiling point of pure water increases on the addition of soluble substances such as sugar or common salt.
