What is the relationship between a state function and an exact differential? Match the items in the left column to the appropriate blanks in the sentences and the equations on the right. Reset Help In order for a function f(r,y) to be a state function, it must be possible to write the total differential df in the form df dr + dy If the form df as written exists, it is an exact differential

As we have seen, the total differential for a state function f (x, y) (an exact differential) can be written df =[∂f/∂x]y dx + [∂f/∂y]xdy The Euler criterion for the exactness of a differential states that the differential is exact if and only if df = M(x, y)dx + N(x, y)dy = ∂N [∂M/∂y]x = [∂N/∂x]y State whether the following differentials are exact or inexact. a) dq = CvdT + (RT/V) dV (assume that Cv and R are constants) b)...

problem 34
Equations with the Independent Variable Missing. If a second order differential equation has the form y"f(y, y), then the independent variable t does not appear explicitly, but only through the dependent variable y. If we let y', then we obtain dv/dt-f(y, v). Since the right side of this equation depends on y and v, rather than on and v, this equation is not of the form of the first order equations discussed in Chapter 2. However, if we...
