1.	When a sample of a gas is compressed at constant temperature from 15 atm to 60 atm, its volume changes from 76 cm^3 to 20.5 cm^3. Which of the following are possible.
Answer» The gas SHOWS non-ideal behaviour The gas dimerizes The gas is adsorbed onto the vessel walls The gas molecules have REPULSIONS to each other Solution :`P_1V_1 = 15 xx 76 = 1140` `P_2V_2 = 60 xx 20.5 = 1230` = non ideal behavious If it was ideal, `V_2 = 19` `= V_r > V_i = Z > 1 = ` repulsions dominate.
