Why can more sugar be dissolved in hot water than cold water (more solute be dissolved in hot solvent then cold solvent)

1 answer:

4 0

Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. when water is heated, the molecules gain energy and because of that, move faster. as they move faster, they come in contact with the sugar more often, causing it to dissolve faster.
