1) The following graph is obtained for the physisorption of gas as a function of pressure at different temperatures. The correct order of temperature is A) T3 < T2 < T1 B) T2 < T3 < T1 C) T2 < T1 < T3 D) T1 < T3 < T2 Answer: Option BExplanation:The degree of absorption increases with the decrease in temperature. The correct order of temperature is T2 < T3 < T1
