    You can use a version of Antoine equation, which is valid for high pressures and temperatures. For example use this one, which is valid in the range of 1°C to 374°C and 4.89 mmHg to 162991 mmHg.

    Calculate a boiling temperature at 25 bar. It is around 224°C. It is more than 200, so we still have water at 200. Not steam.
