Question

which are correct for an ideal gas?
(a) (δP/δVm)=0
(b) (δE/δV)=0
(c) (δE/δP)#0
(d) (δn/δV)#0 [#= not equals to]

Answer 1

According to the definition of the ideal gas, the internal energy of ideal gas doesn’t depend on neither volume, nor pressure. Thus, the (c) statement isn’t correct and the correct one is (b). As for the (d), it isn’t also correct as every gas volume is linear proportional to its quantity ‘n’. The first statement isn’t correct as it doesn’t have sense. Then, the (b) is correct.
