Water becomes a gas at 100 degrees celsius at sea level. Under normal conditions, it can not get any hotter. When the pressure is increased, however, the temperature at which water boils increases. So gaseous water (steam) at 257 degrees celsius, under pressure, would be considered "superheated steam."

water changes from liquid to vapour at this point.
Therefore, water at 250 degree Celsius is in vapour state.

∙ 8y agoWater changes from a liquid to a gas at temperatures from 100 Celsius, so at the given temperature of 257 Celsius, water is definitely a gas (assuming at standard atmospheric pressure).

The temperature of the water would be 4.58333 degrees Celsius higher.
Why is the temperature of the water bath kept at 37 degree Celsius?
because our body temperature is 37 degree Celsius
What is the physical state of water at 250 degree Celsius?
The boiling point of water is 100 degree celsius. Therefore water changes in to vapor after 100 degree celsius. Therefore the physical state of water at 250 degree celsius is "Gas".
Physical state of water at 250 degree celsius?
water at 250 degree Celsius exists in gaseous state
What is the the temperature of water?
25 degree celsius
Why water vaporize at 70 degree Celsius?
70 degree Celsius is qiute a high temperature. in this temperature, the water molecules starts escaping which results in the vapourisation of water.
What is physical state of water at 0 degree celsius?
Water freezes at 0 degree Celsius
What temperature shows water in solid state?
Water turns into a solid when it freezes. It does this at 32 degrees Fahrenheit and 0 degree Celsius.
What happens to a water at a temperature of 20 degree celsius when it is placed into a freezer set at -10 degree celsius?
It freezes
What is the temperature of water as its boiled and heated?
100 degree Celsius
What is the state of water at -35 degree Celsius?
Frozen.
Temperature of boiling water at sea level?
100 degree celsius
If a cup of water of temperature 50 degree celsius is mixed with another cup of water of temperature 50 degree celsius the final temperature of the two combined cups of water will be 100 degree?
No, as both the temperatures are the same, you will get only 2 cups, each 50 degrees. You have to heat the cup to get 100 degree.
