1. Evaluate the value of constant A and β from following relation
dnc = 4πN(m/2πkT)3/2C2e-mC2/2kTdC
2. During change in state for 3 moles of an ideal gas the temperature change by 2K at both constant V and p. Calculate ?U and ?H (given Cp=5/2R).
3. State third law of thermodynamic. what is its limitation also derives its mathematical form.
4. State second law of thermodynamics in as many forms as possible and show that they are identical in significance.
Draw the structure of a DNA nucleotide represented by the abbreviation "C." Do not include formal charges on the phosphate group.
