Hi DrDu, do you mind responding to my earlier question: "My only question remains then: given the information you just stated, for situations where temperature is not a constant, why are the boiling point temperatures of a liquid higher at higher pressures? Shouldn't the favorable increase in...
Hi PeterDonis, yes I read this and I was having trouble understanding this sentence. I didn't know what the author meant by 'narrowing the potential energy well'.. as I mentioned earlier in the thread, I have never taken a thermodynamics course, so my understanding of thermodynamics is very...
Hi DrDu, thank you for your post. It makes a lot of sense to me! My only question remains then: given the information you just stated, for situations where temperature is not a constant, why are the boiling point temperatures of a liquid higher at higher pressures? Shouldn't the favorable...
That's fair. Just to clarify though - in cases when a non-condensible gas is added such that it increases the total pressure exerted on the liquid, what happens when temperature is not constant? Would temperature rise?
I'm just trying to reconcile the following two ideas:
1) If we increase...
Ah... I'm sorry I still am confused. While I can follow along with the math, I need to be able to rationalize the math in my head in layman's terms. So at constant temperature, the equation tells us that there will be a change in free energy of the pure liquid due to an increase in total...
Sorry if this seems like a dumb question: but why does the increase in total pressure cause the free energy of the pure liquid A to increase? (I know you referenced the equation but I'm trying to understand conceptually why increase in pressure leads to increase in free energy of the liquid?)...
Thank you for your response! No I am not familiar with this. Do you mind explaining this relationship conceptually instead?
If the difference btwn molar Gibbs free energy of the species in liquid and the partial molar Gibbs free energy of the same species in gas phase is equal to zero, then...
Hi Chestermiller, I actually have not taken a course in thermodynamics, but I am familiar with Gibbs free energy to some extent as it's been taught in general chemistry courses. I do know that when we're talking about escaping tendency we are actually referring to Gibb's free energy (the phase...
Hi Bystander, okay so you're saying that rather external pressure applied to a liquid has approximately no effect on the liquid's transitioning. Ah, I'm not familiar with the Poynting correction...
I was reading an online chemistry textbook that said "when a liquid is subjected to hydrostatic pressure (for example, by an inert, non-dissolving gas that occupies the vapor space above the liquid surface), the vapor pressure of the liquid is slightly raised." (link...
