22. He(g) (n mole) is taken from state 1 (P1, V1) to state 4 (P4, V4) through state 2 (P2, V2) or
state 3 (P3, V3). Assuming He(g) obeys ideal gas law, choose the correct statement.
(A) w = 0 from state 2 to state 4.
V.-30 L
(B) q= from state 1 to state 2.
(C)△H = n from state 1 to state 3.
(D) △H = q from state 3 to state 4.
(E) Pathway A (through state 2) and pathway B (through state 3) have the same △H.
