Thermodynamics - property relationship of 2 systems

  1. Jun 9, 2016 #1
    1. The problem statement, all variables and given/known data
    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?

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

    3. 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.

    Is this the exact problem statement?
