Adding thermal energy (heat) to a substance will (Hint think about particle arrangement in a gas compared to particle arrangement in a solid)
O decrease the molecular forces that hold molecules together
O increase the molecular forces that hold molecules together
O have not effect on the molecular forces that hold molecules together
O increase and then decrease the molecular forces that hold molecules together
