Chapter 9: Problem 2

The mathematical form of the first law of thermodynamics is (a) \(d q=d U=d w\) (b) \(d q=d U-d w\) (c) \(d U=d q+d w\) (d) none of these

Short Answer

Expert verified
(b) \(dq = d U - d w\)

Step by step solution

01

Identify the correct mathematical form

Compare each of the given choices (a), (b), (c), and (d) with the true mathematical form of the first law of thermodynamics. The correct formulation is \(d U = d q - d w\).
02

Match the correct choice

Upon comparison, it's clear that (b) \(dq = d U - d w\) matches with the correct mathematical form of the first law of thermodynamics.
