1.	Assertion (A): Compressibility factor for hydrogen varies with pressure with positive slope at all pressures Reason (R):Even at low pressures, repulsive forces dominate in hydrogen gas.
Answer» A & R are true, R explains A A & R are true, R does not explain A A is true R is false A is false R is true Solution :Z for `h_1 = 1 + P (b/(RT))` i.e., `Z > 1 implies ` repulsive forces.
