1.	Which system possess eqilibrium from the following ?(i) Saturated solution of sugar in open cup.(ii) At constant temperature mercury in thermometer and its vapour(iii) boiling water in open vessel(iv) floating ice in water at 0^@C(v) ice in water at 15^@C.
Answer» Solution :(iii) and (v) is not EQUILIBRIUM. (i) Sugar solid `hArr` sugar `sol^n` equilibrium (ii)`Hg_((s)) hArr Hg_((g))`(con.temp) equilibrium (iv)`H_2O_((s)) hArr H_2O_((L))` (`0^@` C, 1 atm) equilibrium (v) It is not equilibrium as in short time ice will DISSOLVE in WATER.
