Over 1 oC water is a liquid.
Water can remain liquid at a temperature above 100 degrees, C., when the pressure on it is greater than the pressure found at average sea level.
By decreasing the pressure or using impure water.
YES!!! Providing the gas pressure above the water is sufficianelty higher than atmospheric pressure.
After 100 0C at standard pressure water become a gas.
On the Fahrenheit scale, the freezing temperature of water is 32 degrees at atmospheric pressure. On the same scale, the freezing temperature of gold is 1,948 degrees at atmospheric pressure.
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.
The water is kept under pressure, which raises the boiling point of the water (the same concept behind pressure cookers). Therefore, the water will still be liquid at temperatures greater than 100 degrees C.
At standard atmospheric pressure*, water has gaseous form (water vapor) at 150°C Water freezes at 0 degrees Celsius. Below this temperature it is ice (solid). Water boils at 100 degrees Celsius. Above this temperature it is water vapor (or steam), a gas. *It depends on the air pressure. At normal pressure, the boiling point of water is 100 degrees Celsius, so at 150 degrees the water will be a gas (steam). However, if you put the water under enough pressure, you can keep it liquid even at very high temperatures.
Liquid water can exist at (and above) 100 degrees Celsius if the pressure is increased above one atmosphere (about 100 000 Pascals). The high pressure squeezes the molecules together, and does not allow them to separate into a gas. This forces it to remain as a liquid, despite the high temperature. Of course, water vapour (steam) can certainly exist above 100 degrees Celsius.If you're interested in how the two phases exist together, if you heat water to 374 degrees Celsius and increase the pressure to 218 atmospheres, the properties of the liquid and the vapour merge together to form only one "supercritical fluid" phase.
A formula doesn't exist; this depends on the temperature, pressure, room volume, amount of water, etc.
At sea level water boils at 100 degrees C. Take your pan of water to the top of Everest and ,because there is less atmosphere at 29,000 feet, the water boils at around 90 degrees C. Put your pan of water in a sealed metal container and heat, the water boils above 100 degrees according to the amount of pressure within the pressure chamber. In steam locomotives the water in the boiler is under pressure and then superheated ,ending up at over 300 degrees C.
100 degrees Celsius is the boiling point of water. This does not mean that all of the water is going to evaporate; it means that there is a balance between liquid water and water vapor. Some water will stay liquid while some evaporates. Therefore, the temperature of water can be continually increased. Also, if there is more pressure, the water tends to remain liquid.
