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".
It just remains as water. The freezing point of water is 0 degrees Celsius, while the freezing point is 100 degrees Celsius. Therefore at 20 degrees Celsius, there is no change in state and it just remains as water.
The specific heat of water is 1 calorie per gram per degree Celsius 1 cal/g/degree celsius
water at 0 degree Celsius
0 degrees Celsius.
Gasoline has a less boiling point (72 degree Celsius) While water has a bigger boiling point (100 degree Celsius)
water at 250 degree Celsius exists in gaseous state
Water freezes at 0 degree Celsius
Frozen.
Liquid state
Vapor (gas).
Ice
At O oC water freezes and becomes ice. So, it is in solid state.
At sea level (1 atmosphere), water is a liquid at 25 degrees Celsius. The freezing point of water at sea level is zero degrees Celsius, and the boiling point is 100 degrees Celsius.
Frozen.
Water is a gas (steam) at 120 degrees Celsius.
Water freezes at 0 degrees Celsius
When liquid water freezes to form ice, the chemical composition of water does not change. It will be H2O whether it is in liquid state or solid state. So it is a physical change and not a chemical change.
