Water is in the liquid phase at 75°C and 9 atm pressure. At this temperature and pressure, water exists as a liquid due to the combination of temperature and pressure conditions present.
The melting point of water decreases as pressure increases from 1 atm. At pressures above 1 atm, water requires a lower temperature to melt because the increased pressure helps to stabilize the solid phase.
At the standard atmospheric pressure of 101325 Pa water boils exact at 100 degrees Celsius.
At 0 ATM the boiling point is extremely low. For example at 0.0000034 ATM, the boiling point is -67.78 Celsius. In an ideal vacuum it would be even lower than this but I don't know if it would be 0K or not.

critical point of water is that point on the pressure-volume phase diagram of the water,above which there will be no line of the equilibrium between liquid and gas phase. That means that above this pressure it is not possible to get liquid again by increasing the pressure of the mixture.if we will do so then it will get converted to subcritical fluid i.e.a highly compressed gas. This happens because the interatomic forces at that presure are much more then the forces because of pressure that are trying to change the state of the gas. the values for water are 218 ATM pressure and 374 centigrade.. i hope datas are correct:)
Water is in the liquid phase at 1 ATM pressure and 150 degrees Celsius. At this temperature and pressure, water exists as a liquid.
Gaseous. If that is 150 degrees C, that would be steam.
As pressure is increased from 0.8 ATM to 1.2 ATM at 100 degrees Celsius, the boiling point of water also increases due to the higher pressure. This means that the water will remain in liquid form rather than boiling into steam until the new, higher boiling point is reached.
water changes from a gas to a solid to a liquid
At -50°C and 1 atm, the substance is in the solid phase. With an increase in pressure to 3 atm, the phase transition will occur from the solid phase to the liquid phase.
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.
Water is in the liquid phase at 75°C and 9 atm pressure. At this temperature and pressure, water exists as a liquid due to the combination of temperature and pressure conditions present.
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.
Water changes from gas to liquid to a solid
At 212 oF, water boils at 1 atm of pressure.
As pressure increases from 0.8 ATM to 1.2 ATM, the boiling point of water also increases. Therefore, at 100°C and 0.8 ATM, water would boil, but at 1.2 ATM, the water would need to be heated to a higher temperature to reach the new boiling point under the increased pressure.
The answer depends on the substance. Some substances will be solid, some liquid and some gas.
