Question

A student is trying to dissolve 20 grams of sugar in a beaker containing 250 milliliters of water at room temperature. What can the student do to make the sugar dissolve faster in the water?

Answer 1

They can warm up the water. Sugar dissolves much faster in warm/hot water.

A perfect example of this is when you put sugar in your hot coffee/tea -> it will dissolve almost immediately. If you put sugar in cold water, you will have to stir it for quite some time before it dissolves.
