Explain why a pure solvent shows a level horizontal curve as solidification occurs?

Answer 1

A pure material has a specific freezing point. At this point the temperature will not change until all of the material has solidified. The same thing occurs at the boiling point of a pure liquid. All of the energy goes into a change of state of the material instead of changing the temperature of the system.

Answer 2

curve in what words? Are you're speaking gadget temperature as against time? A organic gadget is univariant. you are able to in basic terms replace one element at a time. As you alter area, temperature continues to be consistent. In a multi-ingredient gadget, you are able to replace 2 (or greater) issues on a similar time. once you reason a area replace, the solid isn't a similar composition because of the fact the liquid, and this differences the composition of the the rest liquid. The freezing element won't stay comparable to you alter the composition of the liquid. The freezing temperature will migrate in the direction of the freezing temperature for the organic substance that's last (being focused) in the liquid. quite, the composition of the liquid strikes in the direction of between the organic endmember components as you get rid of the different organic constituent by technique of solidification. uncertain if that's what you have been asking approximately.
