In Charles Law:
A) Pressure is Kept constant
B) Number of moles of gas is constant
C) Volume is directly proportional to temperature
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. A, B, C are true.
In Charles's Law, the following conditions are true:
A) Pressure is kept constant.
B) The number of moles of gas is constant.
C) Volume is directly proportional to temperature.
Charles's Law states that at constant pressure, the volume of a fixed amount of gas is directly proportional to its absolute temperature (measured in Kelvin). Mathematically, V∝T or V/T= constant. This relationship explains that as temperature increases, the gas expands, and as temperature decreases, the gas contracts.
