Chemistry - Ideal Gas Question with Solution | TestHub

Explain Question: The question asks which of the given curves does not represent Boyle's Law.

Concept: Boyle's Law states that for a given amount of gas at constant temperature, the pressure $(\mathrm{P})$ is inversely proportional to volume (V).

Mathematically: $\mathrm{PV}=$ constant $\to \mathrm{P}\propto 1/\mathrm{V}$

Solution: Boyle's law is also called constant temperature law. For an ideal gas at an particular temperature the pressure becomes inversally proportional to volume of gas.

$\mathrm{PV}=\mathrm{nRT}$ (Ideal gas equation)

If temperature is kept constant.

$\mathrm{PV}=$ constant

$\mathrm{P}\propto \frac{1}{\mathrm{V}}$

Final Answer: Option (c) does not represent the boyles law.
