Is the temperature at which water boils at the seashore is less or greater than that at a Himalayan peak?
The boiling point of water decreases with altitude, so the temperature at which water boils would be lower at a Himalayan peak compared to the seashore. This is because air pressure decreases with increasing altitude, which affects the boiling point of water.
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 temperature does water condensed and turn into a gas?
This is not a cut and dry answer. The temperature that water evaporates to a gas and conversely condenses to a liquid is dependent on air pressure. Liquid boiling points can also be affected by impurities in the liquid, depending on the concentration of impurities. Thus in a pressure cooker water boils at a much higher temperature that it would under normal atmospheric pressure. This is also why you can't make a decent cup of tea on the summit of Everest because water boils at about 71 degrees Celsius at that reduced atmospheric pressure. So it is impossible to give a specific figure for this question.
Is pressure cooker an example of the application of Charles' law?
yes pressure cooker is an example for both charles' law and boyle's. under constant volume temperature is directly proportional to pressure, where the pressure is directly proportional to temperature. so when the stove heats the cooker it increase the in the pressure which in turn increase the internal temprature and cooks the food faster....
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 does the water in the pressure cooker boils even if the flame is put off?
The temperature remains high for a while.
The temperature in which water boils inside a pressure cooker is lower than in an open pan at sea level?
it doesnt it just boils it faster.
How does a pressure cooker demonstrate the effect of air pressure on waters boiling point?
Vapour rom the boiling water is not allowed to escape and so the pressure above the water increases. This raises the temperature at which the water inside the cooker boils.
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.
How do pressure cookers work and are they really much quicker?
Pressure cookers work because when you increase pressure, water boils at a higher temperature. Water normally boils at 212 degrees F. Under 15psi of pressure (standard in a pressure cooker), it boils at 257 degrees F. Since your food is cooking at a higher temperature, it will cook faster.
How can you change the boiling point of liquid?
You can change the boiling point of a liquid by adjusting the pressure on the liquid. Increasing the pressure raises the boiling point, while decreasing the pressure lowers it. This is why water boils at a lower temperature at higher altitudes where the atmospheric pressure is lower.
What is the principle involved in pressure cooker?
The principle involved in a pressure cooker is that increasing the pressure inside the cooker raises the boiling point of water, allowing food to cook at higher temperatures and reducing cooking time. This results in faster cooking and tenderizing of tough cuts of meat.
Is the temperature at which water boils at the seashore is less or greater than that at a Himalayan peak?
The boiling point of water decreases with altitude, so the temperature at which water boils would be lower at a Himalayan peak compared to the seashore. This is because air pressure decreases with increasing altitude, which affects the boiling point of water.
How does pressure affect the temperature at which water boils?
There is a direct relationship between the temperature at which water boils and the air pressure on it. Higher pressure, higher boiling point. Lower pressure, lower boiling point.
What temperature does water boils to?
Fresh water under atmospheric pressure boils at 100 C or at 212 F
Why food is cooked in pressure cooker?
An increase in pressure allows an increase in the boiling temperature of the liquid in the cooker. At 15 psi (the highest rated home kitchen pressure cooker) the boiling temperature of water is 250 degrees F.
The temperature inside a pressure cooker is 117 C Calculate the vapor pressure of water inside the pressure cooker?
At 117°C, the vapor pressure of water is approximately 2566 Pa.
