Water freezes at 0 degrees Celsius
At 500 deg Celsius, it is a vapour.
Water at -20 degrees Celsius; heat will expand matter, so at +40 degrees Celsius, water would have less density. * * * * * That would be true if there were no phase change. Unfortunately for the above answer, water freezes at 0 deg C and that phase change is accompanied by an expansion. As a result, water at 40 deg C is denser that water (ice) at -20 deg C.
At 500 deg Celsius, it is a vapour.

At normal pressure, anything from 50 to 100 deg C.

it would be a gas
There is not a constant difference. At the freezing point of water, 0 deg Celsius = 32 deg Fahrenheit - a difference of 32. At the boiling point of water = 100 deg C = 212 deg F, the difference is 180.
On the Celsius scale, pure water, at normal atmospheric pressure, freezes at 0 deg C and boils at 100 deg C.
25 deg. Celsius is about "room temperature," and assuming normal pressure (1atm) carbon dioxide is a gas.
