71hahahh! Try the rest two in the first post.. they are really good and easy looking questions.
At 298K, the thermal expansion coefficient and the Isothermal compressibility of liquid water are \beta =2\times 10^{-4} \;\;\text{K}^{-1} and \kappa =4\times 10^{-6} \;\;\text{bar} respectively. Then, \left(\frac{\partial \text{U}}{\partial \text{V}}\right)_T for water at 300 K and P = 1.00 bar is :
a) 1.5 * 10^4 bar
b) 3 * 10^-4 bar
c) 6 * 10^-4 bar
d) 9 * 10^-4 bar

71Q: In Solid PBr5, maximum number of d orbital(s) that take part in hybridization of P is X, then X is ?
Ans: 0
Q: No. of vibrational degrees of freedom of CO2 is ?
Q: Write tthe most appropriate structure of C3O2 ?
262since solid PBr5 exists as [PBr4 ]+ Br-
hence it is sp3 hybrid.
262in a linear molecule ,number of vibrational modes is 3N - 5, where N is the number of atoms in the molecule .
hence for CO2 , ans is 4
71For degree of freedom question, Do we have some more formulas like it in thermodynamics?. I didn't knew of any such formula.
