The greater the mass of gas taken, the greater will be the slope of a straight line. Because the greater the _greater be volume occupied.
Correct answer: C. Number of moles
- A. Pressure
- B. Temperature
- C. Number of moles
- D. All of these
Explanation
Option A is incorrect as greater pressure decreases the volume of a gas. Option B is incorrect as temperature increases so volume increases, however, the question is talking about the mass of the gas-only therefore the option is incorrect. Option C is correct as according to the formula n × 24 = Volume increasing the "number of moles" increases volume.

About Charles's Law
At constant pressure, the volume of a fixed mass of gas is directly proportional to its absolute temperature. Questions involve the Kelvin scale, the equation V₁/T₁ = V₂/T₂, volume-temperature graphs, and the need to distinguish Charles's law from Boyle's law, which relates pressure and volume.
