a pressure cooker saves both time and fuel in cooking because inside the cooker, the
boiling point of water is raised
pressure is constant
heat is completely trapped
temperature is evenly distributed
volume of steam varies

The trapped steam increases the atmospheric pressure inside the cooker by 15 pounds per square inch (psi), or 15 pounds above normal sea-level pressure. At that pressure, the boiling point of water is increased from 212°F to 250°F. This higher temperature is what cooks food faster.
When atmospheric pressure increases, the boiling point becomes higher, and when atmospheric pressure decreases (as it does when elevation increases), the boiling point becomes lower.
How is it D. When A is there. Please myschool check your answer... Pressure is raised in a pressure cooker
