Naming Organic Compounds

Would adding up the numbers in the organic compound name and then finding which one has the lower number work in seeing which one is the correct way to name a compound?
4-ethyl-2, 2-dimethyl-hexane (4+2=6)
3-ethyl-5,5-dimethyl-hexane (3+5=8)

The answer for the question is ΔG and ΔSsys, but I was wondering how come it wouldn't be ΔSsys and ΔSsur as well? Won't they both be 0 because it is isothermal and there is no change?

Ideal Gas Equation [ENDORSED]

The ideal gas equation is U(tot)=(3/2)nRT.
Why is 3/2 the constant as opposed to any other number?
