How Does Container Volume Affect Vapor and Liquid Densities in Saturated Fluids?

For question 1, you need to compare the density of the vapor in both containers. For question 2, you need to compare the density of the liquid in both containers. For question 3, you need to compare the amount of vapor in both containers. In summary, the conversation is about two containers with saturated fluid at T0, with different total volumes (V1 and V2), and the definition of total molar volume. The problems are to compare the density of vapor and liquid in both containers, as well as the amount of vapor in each container. The overall density of container 2 is greater than that of container 1 due to V2 being greater than V1, and for problem 3, the amount of

Homework Statement


Two containers with saturated fluid at T0, while having different total volume V1 and V2
definition of total molar volume: total liquid + vapor volume divided by the total moles

Problems:
1. Compare the density of the vapor in both containers
2. Compare the density of the liquid in both containers
3. Compare the amount of the vapor in both containers

Homework Equations

The Attempt at a Solution


I know that the overall density of container 2 is greater than that of container 1 as V2>V1, but I have no idea how to identify the vapor or liquid density just by comparing those two points, so for problem 1&2, I have completely no clue
For problem 3, I assume that the amount of vapor is greater in container 2 as it is closer to the vapor region, but I'm not sure whether this explanation is reasonable
Any help would be appreciated!

What is a P-V diagram?

A P-V (pressure-volume) diagram is a graph that shows the relationship between pressure and volume for a particular system. It is commonly used in thermodynamics and fluid mechanics to analyze the behavior of gases and liquids.

What does the shape of a P-V diagram represent?

The shape of a P-V diagram represents the thermodynamic process or cycle that the system undergoes. The slope of the line on the diagram indicates the change in volume for a given change in pressure, and the area under the curve represents the work done by the system.

What information can be obtained from a P-V diagram?

A P-V diagram allows for the determination of key thermodynamic properties, such as pressure, volume, temperature, and work done. It can also be used to analyze the efficiency of a thermodynamic process and to predict the behavior of a system under different conditions.

How do you interpret a P-V diagram?

To interpret a P-V diagram, first identify the type of thermodynamic process or cycle being represented. Then, analyze the slope and shape of the curve to determine the work done by the system and the change in volume and pressure. Finally, use the diagram to calculate any desired thermodynamic properties.

What are the limitations of a P-V diagram?

A P-V diagram assumes ideal conditions and does not account for factors such as friction, heat transfer, and non-ideal gas behavior. It also only provides a snapshot of a system at a specific point in time, and cannot show the progression of a process or cycle. Additionally, it may not accurately represent complex systems or processes with multiple phases.
