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.
What gas law could apply to how pressure cooker works?
Boiling point = temperature where the vapour pressure is equal to the pressure of the atmosphere above the liquid. When you have a pressure cooker, the pressure above the water is higher than atmospheric pressure, therefore the boiling point of water is elevated to above the boiling point in an open pot. The water temperature exceeds 100 degrees Celsius, and thus the cooking process is accelerated.
Why is the pressure inside an airplane maintained at ground level atmospheric pressure?
i dont know much about it all i know is i have the same doubt
Why it is easy to remove air from balloon than from bottle?
This is because the air inside the balloon is a fairly high pressure than the atmospheric pressure air outside the balloon. On the other hand air pressure inside the glass bottle is already equal to the atmospheric pressure so it is difficult to remove air from a glass bottle.
How does the human body resist the atmospheric pressure?
because our body pressure is equal to the atmospheric pressure.
What is the pressure inside the pressure cooker when closed but no heating will it be equal to atmospheric pressure or not?
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.
The temperature inside a pressure cooker is 117 C Calculate the vapor pressure of water inside the pressure cooker?
2.90
What is The temperatur inside a pressure cooker?
Depends on the set pressure.
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 ,
What is the air pressure inside the pressure cooker after the safety valve melts?

Why does your head not get crushed with atmospheric pressure?
Like the air inside a baloon, the fluids inside your body exert pressure. This pressure inside your body acts against atmospheric pressure. I was looking for the answer for a school assignment! Textbooks help!
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.
Is the pressure inside the balloon equal to the atmospheric pressure?
Think about this: if the pressure WERE equal, what would happen in the instant when you open the neck of the balloon and whatever pressure is on the inside meets the pressure that is on the outside (atmospheric pressure)? In your experience, what DOES happen?
What is the pressure cooker also called?
A pressure cooker is a cooking vessel that is enclosed with a lid that seals to the pan with a rubber gasket, which cooks at a pressure that is higher than the atmospheric pressure. These cookers are usually made of thick-wall stainless steel or thick aluminum. In the lid is a small vent-hole that contains a pressure-regulating mechanism. Water in the food being cooked will boil and cause a steam build-up in the vessel, which will increase the pressure inside the vessel. The pressure-regulating mechanism on the vent-hole will allow some steam out if pressure exceeds a certain limit (usually around 15 psi, or 15 pounds per square inch), thus maintaining a more or less constant pressure inside the pressure cooker that is higher than atmospheric pressure. Since the boiling point increases with higher pressure (for example, water boils at 100 degrees C at atmospheric pressure but it will boil at a higher temperature inside a pressure cooker since the pressure inside is higher), the temperature inside a pressure cooker can rise more than it would have in an open-enclosure pan. Because of the higher temperature, meat becomes soft easily and food cooks faster causing less loss of nutrients. Pressure cookers often have various safety mechanisms to prevent the buildup of excessive pressure and exploding. After cooking is finished, it is important to release the steam slowly first, because if the lid is opened suddenly, a large amount of steam escaping can cause scalding. Many pressure cookers have special mechanisms for controlled steam release before opening the lid.
At what degrees the water boils in a pressure cooker?
Above 100 deg C The extent to which the temperature is higher than 100 deg C depends on the pressure inside the cooker and that is controlled by the weights on the cooker valve.
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.
