Consider a ball at the end of a string. If the ball is swinging back and forth, at what point in the swing would the ball have the most potential energy? You are digging out a soil sample and first find a thin layer of topsoil. Underneath this layer, you see a larger layer of very fine particles that is still fairly wet and somewhat gray in color.

Dissolving a solute in water lowers its freezing point. Ionic substances like salt lower the freezing point more than covalents due to dissociation of ions. Dissolving a solute in water raises its boiling point. Ionic substances like salt raise the boiling point of water so you can raise the heat of water without boiling it and also cook the pasta at the same time.
