I'm having trouble understanding the concept of a state function, particularly relating to enthalpy, which is, and heat and work, which are not. I don't understand the why of this very well.

Note: Yes, this is homework. But no, I am not intending to copy straight the answers from here, however if you can work me through most of it (as opposed to just hints) that would be helpful. This way, I can take your lead, work my way though it, and have help should I get stuck again. Thank you!

8. Suppose that f is differentiable with derivative f '(x) = (1 + x^3)^(-1/2). Show that g = f ^ (-1) satisfies g''(x) = (3/2)*g(x)^2.

22. a. Prove that an incresing and decreasing function intersect at most once.
b. Find two continuous increasing functions f and g such that f(x) = g(x) precisely when x is an integer.

25.b. Prove that if a function is differentiable and nondecreasing, then f'(x) >= 0 for all x.
c. Prove that if f'(x) >= 0 for all x, then f is nondecreasing.

13. Supopse that f is a continuous increasing function with f(0) = 0. Prove that for a,b > 0 we have:
a*b =< integral (0 to a) f(x)dx + integral (0 to b) f ^ (-1) (x)dx
and that equality holds if and only if b = f(a).

A disk rotates about its central axis starting from rest and accelerates with constant rotational acceleration. At one time it is rotating at 10 rev/s; 60 revolutions later, its rotational speed is 15 rev/s. Calculate (a) the rotational acceleration, (b) the time required to complete the 60 revolutions, (c) the time required to reach the 10 rev/s rotational speed, and finally (d) the number of revolutions from rest until the time the disk reaches the 10 rev/s rotational speed. What equations would you use, and can you explain your answer?
