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.
