Question

Hello, Can you please answer these two questions for me? Thanks!

4. The specific heat Cp of a substance is given by Cop=a+BT where a = 20.35 J/K and b = 0.2 J K¹² Calculate the change in entropy in increasing the temperature of this substance from 298.15 K to 304.0 K. 5. What is the entropy of 1.00 L of N2(g) at T = 350.0K and p = 20.25 atm given that the standard (p = 1.00 bar, T = 298.15K) molar entropy 011 mS 191.6J/K mol)? (Calculate the molar amount of N2 using the ideal gas equation.)
