Question

In two beakers ($A$ and $B$) $50ml$ water of about ${70}^{o}C$ each is taken. Then in beaker $A$, $50ml$ of water of about ${30}^{o}C$ is added and after 5 minutes, in beaker $B$, $50ml$ of water of about ${30}^{o}C$ is added. What would observe if the temperatures of both beakers recorded immediately? Why?

Answer 1

No.

The amount of salt and sugar dissolved in water will not be the same at the same temperature.

On cooling the content of the beakers, crystals of salt and sugar will appear.

This is because solubility of a solid decreases with decrease in temperature
