For example, we do not need any chemical reaction to observe the fact that water is odourless in its pure state. Also, we only need a thermometer and no chemical reaction to observe it's boiling point. Physical observation tells us that the liquid turns into vapour at that temperature. This is confirmed by observing the loss in volume of the liquid
