WebScientists refer to the measure of randomness or disorder within a system as entropy. High entropy means high disorder and low energy (Figure 1). To better understand entropy, think of a student’s bedroom. If no energy … WebLike freedom, the entropy of a system increases with the temperature and with volume. The effect of volume is more easily seem in terms of concentration, especially in the case of mixtures. Does entropy decrease with volume? ΔS=q/T, so the higher the temperature, the smaller the change in entropy for the same amount of heat released or absorbed. thornitsWebIf you apply a magnetic field, then the magnetic moments are able to lower their energy by entering a lower entropy state where they are magnetized. In such a material the entropy tends to decrease as magnetic field increase, at least when it is able to give away entropy to its environment.
