Question

In the given V–T diagram, what is the relation between pressures P₁ and P₂?

G1 Physics · Accepted Answer

Step 1: At constant pressure, the ideal-gas equation gives V = (nR/P)T. Step 2: In a V–T graph, slope = V/T = nR/P, so slope is inversely proportional to pressure. Step 3: The line labelled P₂ has a greater slope than P₁. Step 4: Therefore P₂ < P₁. Final answer: (C).
