Water boils at 120 in a pressure cooker why?
Water boils at 120°C in a pressure cooker because the increased pressure inside the cooker raises the boiling point of water. Normally, water boils at 100°C at standard atmospheric pressure, but the pressure cooker traps steam, increasing the pressure and allowing water to reach higher temperatures before boiling. This higher temperature cooks food faster and more efficiently.
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.
What substances boils at 100 degrease?
Pure water boils at 100 degrees at atmospheric pressure.
Can water boil at 150 degrees celsius?
Yes. 150 degrees Celsius is equal to a temperature of 302 degrees Fahrenheit.
When water boils what degree in Celsius does it reach?
Water boils at 100 degrees Celsius at standard atmospheric pressure.
How can water be made to boil at 90 degrees celsius?
Water boils at 100 degrees Celsius at standard atmospheric pressure. To make water boil at 90 degrees Celsius, you would need to increase the pressure acting on the water. This can be achieved in a pressure cooker or by pressurizing the system. At higher pressures, the boiling point of water increases.
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.
Can water boil at 150 Celsius?
No, water boils at 100 degrees Celsius under normal atmospheric pressure. To boil water at 150 degrees Celsius, you would need to increase the pressure above normal atmospheric levels using a pressure cooker or similar device.
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.
Why does the water in the pressure cooker boils even if the flame is put off?
The temperature remains high for a while.
What is you boil at different degrees?
Do you mean how can you boil at different temperatures? You can add lots of salt to the boiling water to raise the temperature. This isn't very effective. The best method is to pressurize the pot (pressure cooker) this will raise the temperature quite a bit, up to 250 degrees at the highest pressure allowed by a pressure cooker. Do you mean what are the different temperature scales and boiling points? water boils at 212 degrees F or 100 degrees C
What boils at 96.2 degrees Celsius?
Water boils at 104 degrees celsius, I think.
