Question

In the equation $\left(P+\frac{a}{V^2}\right)\left(V-b\right)=$ constant, the unit of a is

• A. $\text{dyne}\times c{m}^5$
• B. $\text{dyne}\times c{m}^4$
• C. $\text{dyne}\times c{m}^3$
• D. $\text{dyne}\times c{m}^2$

Answer 1

Answer: (B)

Units of a and $P{V}^2$ are same and equal to dyne $\times c{m}^4$
