Why Do Pressure Cookers at High Altitudes Have a Higher Actual Pressure Inside?

Is it true that pressure cookers at high altitudes have a higher actual pressure inside compared to those at sea level?

True or False?

Answer:

True

When cooking at high altitudes, the atmospheric pressure decreases, causing water to boil at a lower temperature. This lower boiling point can affect the cooking time of food. Pressure cookers are designed to raise the pressure inside the cooker and increase the boiling point of water, allowing the food to cook faster. At higher altitudes, where the atmospheric pressure is already lower, the pressure inside the cooker needs to be even higher to achieve the desired cooking time. Therefore, pressure cookers at high altitudes have a higher actual pressure inside than those at sea level.
