Thermodynamics - property relationship of 2 systems

In summary, when a pure substance is placed into two containers of the same volume where Container 1 has twice the mass of Container 2, and both containers reach thermal equilibrium with the surroundings, we can conclude that the pressure of Container 1 is twice the pressure of Container 2. Additionally, Container 1 must have half the specific volume of Container 2. This is based on the zeroth law of thermodynamics and the equation specific volume = volume / mass.

Homework Statement


A pure substance is placed into two containers of the same volume. Container 1 has twice the mass of pure substance of Container 2. After the containers are shut and both reach thermal equilibrium with the surroundings, what do we know about:
a) the pressure of Container 1 compared to Container 2?
b) the specific volume of Container 1 compared to Container 2?

Homework Equations


Possibly an ideal gas law, but the question does not specify that the pure substance is an ideal gas.
specific volume = volume / mass

The Attempt at a Solution


The containers must have equal temperature according to the zeroth law of thermodynamics.
Container 1 must have half the specific volume of Container 2.

a) Pv = T, so the pressure of Container 1 is twice the pressure of Container 2.
b) specific volume = volume / mass, so Container 1 must have half the specific volume of Container 2.

Related to Thermodynamics - property relationship of 2 systems

1. What is thermodynamics?

Thermodynamics is a branch of science that studies the relationship between heat, energy, and work. It describes how these three factors interact with each other and how they affect the properties and behavior of systems.

2. What are the laws of thermodynamics?

The laws of thermodynamics are fundamental principles that govern the behavior of energy in a system. The first law states that energy cannot be created or destroyed, only transferred or converted from one form to another. The second law states that the total entropy of an isolated system will always increase over time. The third law states that it is impossible to reach absolute zero temperature through a finite number of steps.

3. How do thermodynamics and properties of 2 systems relate?

Thermodynamics is concerned with the energy and heat transfer between two systems, and how this affects the properties of each system. The properties of the two systems are interdependent and can change as a result of energy and heat transfer between them.

4. What is the difference between an open and closed thermodynamic system?

An open thermodynamic system can exchange both matter and energy with its surroundings, while a closed system can only exchange energy. In an open system, the properties of the system can change due to the exchange of matter and energy with the surroundings, while in a closed system, only the properties related to energy can change.

5. How is thermodynamics used in practical applications?

Thermodynamics is used in a wide range of practical applications, including power generation, refrigeration, and chemical reactions. It is also used in the design and optimization of engines, turbines, and other energy systems. Understanding thermodynamics allows scientists and engineers to predict and control the behavior of systems and improve their efficiency.
