Question

Problem 20a

Answer 1

Given information

We are given that:-

Food cooks faster in a pressure cooker.

Step-by-step explanation

Step 1.

A pressure cooker is sealed, so as the temperature of its contents increases, the number of particles inside and the volume are kept constant. Thus, the pressure increases according to the ideal gas law. Assuming there is water inside the pressure cooker, an increased pressure yields a higher boiling point for the water. The water in which the food is prepared will boil at a higher temperature than normal, thereby cooking the food faster.
