• A. $\frac{x}{m} \propto P^{0}$
• B. $\frac{x}{m} \propto P^{1}$
• C. $\frac{x}{m} \propto P^{1/n}$
• D. All the above are correct for different ranges of pressure

Answer 1

Answer: (D)

All the above are correct for different ranges of pressure

Answer 2

$\frac{x}{m} \propto P^{1/n}\quad\quad$ where $n \ge 1$
