Explain the following statements in terms of the laws of thermodynamics.
(a) Energy can be neither created nor destroyed.
(b) Entropy can be created but not destroyed.
The volume of a substance increases with increasing temperature and decreases with increasing pressure. These properties, respectively are tabulated quantitatively as the cubic expansion coefficient, α = (1/Vm) (δVm/δT)P, and the isothermal compre..
