Mabel conducted an experiment as shown in the diagram below. in each set-up, a conical flask was filled with identical volumes of air at different temperatures. the set-ups were then left until the air in the flasks reached room temperature. state if the red-coloured oil drops in each set-up will increase, decrease or remain at the same height at the end of the experiment. explain your answer in terms of heat gain or heat loss.
(the pic is suggested ans, i don't understand why since i think it should be the opposite)

1. suppose a reaction mixture, when diluted with water, afforded 300 ml of an aqueous solution of 30 g of the reaction product malononitrile [ch2(cn)2], which is to be isolated by extraction with ether. the solubility of malononitrile in ether at room temperature is 20.0 g/100 ml, and in water is 13.3 g/100 ml. what weight of malononitrile would be recovered by extraction with (a) three 100-ml portions of ether and (b) one 300-ml portion of ether? suggestion: for each extraction, let x equal the weight extracted into the ether layer. in part (a), the concentration in the ether layer is x/100 and in the water layer is (30 x)/300; the ratio of these quantities is equal to k 20/13.3.
