Question

If P, V, T represent pressure, volume and temperature of the gas, which of the following is correct representation of Boyle's law?

• A. $V\propto \frac{1}{T}$ (at constant P)
• B. PV = RT
• C. $V\propto \frac{1}{P}$ (at constant T)
• D. $PV=nRT$

Answer 1

The correct option is C

$V\propto \frac{1}{P}$ (at constant T)

According to Boyle's law $V\propto \frac{1}{P}$

$V=\frac{\text{Constant}}{P}$ $\Rightarrow$ VP = Constant.

For a fixed amount of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. Boyle's law states that the pressure and volume of a gas have an inverse relationship, when temperature is held constant.
