An ideal gas of n moles is enclosed in a container at a constant pressure P. The graph between volume of gas and its absolute temperature is a straight line. What is the gradient of the graph?
Correct answer: A. nR/P
- A. nR/P
- B. nRP
- C. n/ RP
- D. nP / R
Explanation
Correct Option: A it is the correct gradient of graph. using the general gas equation PV = nRTV/T = nR/P

About Ideal Gas Equation
The ideal gas equation, PV = nRT, relates pressure, volume, amount and absolute temperature when gas particles are assumed to have negligible volume and no intermolecular forces. Applications include finding molar mass, density or an unknown gas variable, with careful use of Kelvin temperature and consistent units, and comparison with real-gas behaviour.
