<em>You can </em><em>dissolve</em><em> more </em><em>salt</em><em> in </em><em>hot water</em><em> because in hot water, </em><em>molecules </em><em>move faster than </em><em>cold water</em><em> because of the </em><em>higher energy</em><em>, as a result the molecules of hot water move fast and </em><em>settles down</em><em>. As they settle fast, it is easy for higher amount of salt to dissolve in hot water. </em>
