NEET Physics Ideal Gas Equation MCQ Question
What is the relationship between pressure (P), number density (n), and mean squared speed (v) of molecules in an ideal gas as derived from the kinetic theory?
P = (1/3) n m v^2
P = 3(n m v^2)
P = (1/2) n m v^2
P = n m v^3
Correct Answer
Detailed Explanation
The relationship is given by the equation P = (1/3) n m v^2, where n is the number density and v is the mean speed of the molecules. This is derived from the kinetic theory of gases as stated in the NCERT context.
