Hi, could someone please tell me if the vapor pressure should be combined with the air pressure in a sealed vessel to give the total pressure? For example, if I put room temperature water in a test tube (at sea level) with some head space for air and then seal it, the pressure inside would be 1 bar, would it not? If I then heated the water inside to 100C, the vapor pressure should equal 1 bar also, shouldn't it? Does that mean that the air pressure and the vapor pressure combine to give a total pressure of around 2 bar? Or is the total pressure closer to 1 bar because the air pressure decreases the amount of water that can vaporize at the given temperature? I apologize for my somewhat rudimentary questions and many thanks for your help
