We have a suspension of pure liquid o-xylene (mg 106 g mol"1), with a liquid vapor pressure of 8.7 x 103 atm, and an activity coefficient in water of 3.37 x 10*. starting with the fugacity equality f f where e is the pure xylene phase, derive and solve for an expression for the solubility (mg l) of o-xylene in water.

Which of these describes how heat is transferred by convection* a. sunlight travels through space without the aid of fluids or solids. b. warm air rises and takes the heat with it, eventually, it cools and sinks c. air at the equator rises and sinks at the poles. d. air molecules touch the warm ground, heating them up *not conduction
