What would the state of water be at if the pressure is 25 bar and the temp is 200 degrees Celsius?
At 25 bar and 200°C, water will be in its supercritical state, meaning it will have properties of both a liquid and a gas. It will have a high density and low viscosity, allowing it to dissolve substances easily.
As pressure increases, the boiling point of water also increases. This is because the higher pressure prevents the water molecules from escaping as easily, requiring a higher temperature to reach the vapor pressure needed for boiling.
Generally, as temperature increases, the density of water decreases. However, at high pressures and temperatures, the density of water can increase due to the formation of hydrogen bonds between molecules.
No, water cannot exist as a solid at these conditions. The critical point of water, where it can exist in a supercritical state, is at 22.064 MPa (approximately 220 bar) and 374.15°C. At these conditions, water can no longer transition between liquid and solid states.
As pressure and temperature increase, the solubility of substances in water also increases. This is because the higher pressure and temperature allow water to dissolve more substances by increasing the kinetic energy and molecular motion of water molecules.
