Question

you are provided with two samples of water labeled as A and B. Sample A boils at 100°c and sample B boils at 102°c. which sample will not freeze at 0°c? Comment .

Answer 1

B sample has some impurities so it boils at 102 c
So b will not freeze at o c
Whereas a is normal water which boils at 100 c and freezes at 0 c

Hope it helps

Answer 2

I guess both will freeze at 0° as the freezing point of water is 0°
