"At constant pressure, the volume of gas is directly proportional to Absolute Temperature". This is known as:
Correct answer: D. Charles law
- A. Boyle's law
- B. Isothermal process
- C. General gas law
- D. Charles law
- E. Henry's law
Explanation
Charles's law, or the law of volumes, was found in 1787 by Jacques Charles. It states that, for a given mass of an ideal gas at constant pressure, the volume is directly proportional to its absolute temperature, assuming a closed system.

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.
