Gaseous. If that is 150 degrees C, that would be steam.
The water is in the gas phase.
Condensation
At the melting point (Explanation) if you look at the phase diagram and look at the point where the water is 0 degrees C and 1 atm, they meet right on the line. This is the line that shows the melting point of this substance. Therefore, since the point is on the line, water at 0 degrees C and 1 atm is at the melting point.
liquid
The triple point of Carbon Dioxide is 216.58 K (-56.57 °C), 518.5 kPa (5.117197 atm) so pushing the pressure higher and the temperature lower shifts it solidly into the solid phase. Another way of checking it is to note that the vapor pressure of solid Carbon Dioxide at -60 °C is 4.043 atm so increasing the pressure to 15 atm would certainly push it further into the solid phase.
Water will be in a the gaseous form of steam at 150 degrees centigrade. Water begins to boil at 100 degrees centigrade at sea level.
It is in the gas phase.
The water is in the gas phase.
