$\begin{array}{l}2.2 3.3 4.4\end{array}$
(a)PV/RT
(b)RT/PV
(c)PV
(d)RT
Answer
Under review — not yet confirmed.
Answer: D
The source book printed C; on checking, D is correct — see the explanation.
Book printed (c).
Explanation
Comparing PV/RT = 1 + B_P·P with 1 + B_V/V and P ≈ RT/V gives B_V = RT·B_P, so α = RT (d).
