The pressure inside will be the same as what the atmospheric pressure was when the lid was closed as long as no heat is added or removed.

Can you explain the gases in the pressure cooker?

By heating the pressure increase and again the temperature increase.


How food is cooked easily in pressure cooker?

During heating the pressure increase in the pressure cooker; as a consequence the temperature increase, the cooking is faster, part of energy saved, etc.


Why doeswater boil at a low boiling point on top of a mountain and a higher boiling point in a pressure cooker?

This is because the boiling point of any fluid increases as the pressure acting on it is increased. Atmospheric pressure on top of a mountain is lower than normal atmospheric pressure. Conversely, by not allowing steam to escape, the pressure above the water in a pressure cooker is allowed to build up to a much higher level.


Explain the principle of operation for the pressure cooker and the vacuum pan in cooking?

Pressure Cooker Operation In pressure cooker,the food is cooked in closed condition ,where,there is pressure valve ,here you are increasing the pressure inside the vessel hence ,pressure inside the pan will be greater than atmospheric pressure,hence the boiling point is reached in less time and cooking takes place faster. Vacuum Pan Here vacuum is opened or reducing the pressure where air inside is removed and hence the product is cooked at lower temperature .More u increase the vacuum,more reduction in pressure and hence longer time to cook ,


Why is it easier to cook in a pressure cooker?

The universal gas law states that (pressure * volume/temperature) of a gas is a constant. Hence, if the volume stays the same (as in a pressure cooker), the air in the cooker can increase in temperature beyond the boiling point of water as pressure builds up over the normal atmospheric pressure. A higher temperature means faster cooking. The above is a very simplistic view of the physics involved.


What is the advantage of a pressure cooker in the term of physics?

In pressure cooker temperature rises to about 120 degree centigrade due to higher pressure than atmospheric pressure. Witch makes it makes food to get cooked faster than in open pot where water boils at 100 degree centigrade. Pressure cooker becomes essential at high altitude where water may boil at about 70 degree centigrade.

How a pressure cooker can save in cooking food and tenderizing meat faster?

it is a closed system, pressure builds from heat causing trapped steam, thus food cooks faster.
