(∂V/∂T)P is the amount of work done. If we consider this amount of work done, in Cp, i.e, at constant pressure heat is absorbed and work is done, not only to increase the temperature of the gas (or the Substance) but also to increase the volume of the gas (Which, isn't constant here) which...

The relevant principle , I think , is the Archimedes' Principle. According to it, weight in air-weight in liquid=Upthrust experienced. Weight in liquid is the same for both, There is no information about volume or upthrust experienced of the solids. So, I'm pretty much stuck too...

Well, in case of a voltaic cell, when you look at each half cell, since ions are in the solution and atoms in the electrodes, there exists a potential difference here, this shall be its standard reduction potential. When two half cells are combined, the reaction at each electrode actually...

Homework Statement Two solid pieces, one of steel and the other of aluminium when completely immersed in water have equal weights. When these solid pieces are weighed in air, aluminium seems to weigh more. Why is this so? On what factors in this being decided?[/B]Homework EquationsThe Attempt...

Since potential is measured in terms of work done per unit charge, if a charge is moved between two points against the field, then work done is positive and naturally , potential is greater at the second point, so the difference in potential is : (Potential at 2nd point)-(Potential at first...
