For an ideal gas undergoing a state change, which of the following proportionality relationships are — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

Option A is Charles's Law. Option B is Gay-Lussac's Law. Option D is derived from $PV = (m/M)RT \implies P \propto m$ when $V, T, M$ are constant. Option C is incorrect because $PM = dRT \implies d \propto M$ at constant $T$ and $P$, not inversely proportional.
