8. The p-V diagram in Fig. 8 shows two paths along which a sample of gas can be taken from state a to state b, where V_b=3V₁. Path 1 requires that energy equal to 5 p₁V₁ be transferred to the gas as heat. Path 2 requires that energy equal to 5.5 p₁V₁ be transferred to the gas as heat. The ratio p₂/p₁ should be (A)1.5 (B)2.0 (C)2.5 (D)3.0 (E)4.0
