Question

explain why eggs can be made to boil faster in salt water than in pure water​

Answer 1

hala mate,

Let's have a quick chemistry lesson, shall we? Salt increases water's boiling point, or the temperature it must reach in order to boil. This happens through a phenomenon aptly named boiling point elevation, which occurs when what's known as a non-volatile solute, such as salt, is added to a solvent, such as water, to raise its boiling point. It can happen with any combination of non-volatile solute and solvent, not just salt water. This new salt water solution needs more heat to start boiling than pure water does, so the time it takes to boil increases slightly. So your water is hotter, but it's not boiling any faster. The moral of the story: salt improves the taste of your cooking, but not the time it takes.

hope it helps!
