Question

The statement that the volume of a fixed amount of a gas at a constant pressure is directly proportional to its absolute temperature is known as ________ law.

1) Charles's
2) Boyle's
3) Gay-Lussac's
4) Avogadro's

Answer 1

Charles's law states that at constant pressure, the volume of a fixed amount of gas is directly proportional to its absolute temperature in kelvins. The correct option is 1.

Step-by-step explanation:

The statement that the volume of a fixed amount of a gas at a constant pressure is directly proportional to its absolute temperature is known as Charles's law.

Charles's law can be mathematically stated as V = const. · T, where V stands for volume and T for absolute temperature in kelvins.

This law is named in honor of the French scientist Jacques Alexandre César Charles, who was a pioneer in balloon flight. Understanding this law helps explain the behavior of gases under various conditions and is fundamental in the study of thermodynamics and kinetic theory. The correct option is 1.
