The Volume of a fixed mass of gas is directly proportional to absolute temperature and constant pressure as stated by:

Correct answer: D. Charles law

  • A. Daltons Law
  • B. Boyle's Law
  • C. Avogadro's Law
  • D. Charles law

Explanation

Charles' Law states that, at constant pressure, the volume of a fixed mass of gas is directly proportional to the absolute temperature. This can be expressed mathematically as:V ∝ TorV = kTwhere V is the volume, T is the absolute temperature, and k is a constant

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.
