Which law was studied in the year 1787, in which it was said that as the volume of a gas increases its absolute temperature, if its absolute temperature decreases, then itsvolume will decrease?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. Charles's law.
The law studied in 1787 is Charles's Law, named after French scientist Jacques Charles. It states that, at constant pressure, the volume of a gas is directly proportional to its absolute temperature (measured in Kelvin). This means that as the temperature of a gas increases, its volume increases, and if the temperature decreases, its volume decreases, provided the pressure remains unchanged. Charles’s Law laid the foundation for understanding the thermal behavior of gases and later became an essential part of the Ideal Gas Law. It is mathematically represented as V ∝ T or V/T = constant.
