Question

Suppose you cooled a crucible containing a mixture of tin and lead with composition d. What would there be in the crucible at each of the points from d to h? (In general terms such as "a mixture of solid lead and liquid tin") d: a liquid mixture of molten tin and lead e: a liquid mixture of molten tin and lead f: a liquid mixture of molten tin and lead plus some solid tin beginning to form g: a liquid mixture of molten tin and lead plus more solid tin than at f h: a solid mixture of tin and lead

Explanation / Answer

there is a transitino from point d to h. At a it is a moltent mixture of lead and tin. In the process of cooling, tin starts separating from the molten mixture. d to h shows that change.

d : mixture of molten tin and lead

e: Cooling results in no change: mixture of molten tin and lead.

f; Solidification of tin starts separating from the mixture. So molten tin and lead, some solid tin

g : formation of much more tin

h: Soid mixture of lead and tin
