21.   At all vapour pressures and compositions above the line, the mixture is a liquid.

22.   At all vapour pressures and compositions below it, the mixture is a vapour.

23.   Mixture C is a liquid at one atmosphere.

24.   Mixture D is a vapour at one atmosphere.

25.   The vapour mixture is thus proportionately richer in component A.

26.   The mole fraction ofA in the vapour is thus greater than the mole fraction of A in the liquid.

27.   The solid mixture is in equilibrium with the liquid.

28.   There was a mixture of panic and curiosity.

29.   Add the water and beat until the mixture is light and fluffy.

30.   A tantalising mixture of talent is due to appear at the Town Hall in Oxford on Friday.
