consider 1kg of water at 1atm. You seal it with a cover such the confined volume is exactly 1L. That is to say, there is no vacuum space if the system is pure water at 1atm. Is the water still in equilibrium with vapor? If so, how to obtain the vapor pressure in this system?

Answer #1

Now here let us analyze the problem

Cover has been put on top such such that here is no vacuum space.

At normal temperature, say 25 oC, water has some vapor pressure. Water will continue to vaporize until they come in equilibrium. Due to this some amount of water will definitely vaporize and a layer of vapor will be formed on top of water. Once the temperature is known One can make use of Antoine equation to obtain the saturation pressure of Waste, which will be the, vapor pressure ( for this particular case) of water vapor in equilibrium with water

A rigid tank has a volume of 0.01 m3. It initially contains saturated water at a temperature of 200 oC and a quality of 0.4. The top of the tank contains a pressure regulating valve which maintains the vapor at constant pressure. This system undergoes a process where it is heated until all the liquid vaporizes. How much heat in (kJ) is required? You may assume there is no pressure drop in the exit line.

A 50/50 blend of engine coolant and water (by volume) is usually used in an automobile\'s engine cooling system. If your car\'s cooling system holds 6.50 gallons, what is the boiling point of the solution? Make the following assumptions in your calculation: at normal filling conditions, the densities of engine coolant and water are 1.11 g/mL and 0.998 g/mL respectively. Assume that the engine coolant is pure ethylene glycol (HOCH2CH2OH), which is non-ionizing and non-volatile, and that the pressure remains...

Background Almost all animal and plant cells require oxygen and give off carbon dioxide. This is called gas exchange and it occurs by passive diffusion. Some animals do all or most of their gas exchange across their skin (for example amphibians) but they have very low metabolisms and use very little oxygen and get rid of very little carbon dioxide. On the other hand humans (and other mammals) have very high metabolic requirements and we can’t rely on gas exchange...
