Thanks for your answer! I have given some thought to studying in the US but I don't see a compelling reason to go. Everything is so much more expensive there, its it worth it? how much could a MSc cost in the US? 30k€? On the other hand in europe they are much cheaper even free in some...

I am in my last year (4 year total) of my physics studies, I will be graduating as the top 1 or maybe top 2 of my class. I don't have a clue what to do next. These last years I have been getting more "cynical" to say something, don't really know how to express this. I have been losing my love...

I am a physics student from Spain and hopefully I will be finishing my degree in physics (4y) by next June. I am trying to decide on a Master's program to study but I am finding very difficult to decide since there are so many oportunities and so diverse specially when looking for programs...

Let my try to clarify it for you. A heat engine is a machine that transforms heat to work. You should know (2º law of thermodynamics) that heat cannot be completely transformed to work, there has to be some "wasted heat" in this case the heat flowing to the cold reservoir. Otherwise you would...

Let me try to answer. The meaning of impedance in this case is the same as always! you can see it was the relation between the voltage between the terminals and the current going into your (equivalent) circuit (or two-terminal element). It doesn't really matter of it's complex or not, it just...

Homework Statement [/B] You are asked to calculate changes in internal energy, entropy, heat transferred and work done for each of the following process. Also you are asked to calculate "the latent heat for the isotherm in the figure". We know the a and b parameters which characterize the VdW...
