Question

Why food is cooked quickly in a pressure cooker?

Answer 1

$\bf\underline{Answer:-}$

Food is cooked quickly in a pressure cooker because of the trapped steam present inside the cooker.

The temperature i.e., 212°F - 250°F inside is what cooks the food in the cooker.

Answer 2

Answer:

Boiling point of any liquid increases as the pressure acting over the liquid increases. At higher altitudes, atmospheric pressure is low and thus water boils at temperature lower than

Boiling point of any liquid increases as the pressure acting over the liquid increases. At higher altitudes, atmospheric pressure is low and thus water boils at temperature lower than100°C. As a result, the heat provided to open vessel is less, while cooking food for a given period..in a pressure cooker, the pressure is higher than one atmosphere. Due to higher pressure, water.boils at higher temperature than 100°C. Hence more heat is provided for a given time period to cook food and cooking food takes less time. Thus, fuel consumption is less while using pressure cookers to cook food. As it takes less fuel and less time, thus cooking food in pressure cooker is advantageous as compared to cooking in open vessels.
