Can I plot a phase diagram (P against T) of a mixture if the mole compositions are known?

Is it possible? Or do I have to actually experiment it in a lab? If it's possible, what data would I need? I'm right now only given the mole percentages and the weight percentages. I do know I can ...

What is the temperature change for the adiabatic compression of $^3$He?

Given a phase diagram of $^3$He, consider the adiabatic compression of liquid $^3$He until it becomes solid. If the temperature of the fluid is 0.1 K (where dP/dT < 0), will the temperature after ...

Constant Pressure lines in evaporation diagram

Assume that there is the following $T-H$ phase diagram with the constant pressure lines. Which is greater preasure? The preasure drops as we move to lower temperatures (i.e. from top to bottom)? ...
