In Charles's Law, volume of gas is directly related to which factor?
Correct answer: B. Temperature
- A. Pressure
- B. Temperature
- C. Volume
- D. Number of moles
Explanation
Correct option is B. Charles's law states that: "the volume of a given mass of gas is directly proportional to its absolute temperature when pressure is kept constant". The equation for Charles's law is: V1/T1 = V2/T2 where: V1 and V2 are the initial and final volumes of the gas T1 and T2 are the initial and final absolute temperatures of the gas The absolute temperature is the temperature in Kelvin.

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.
