Define entropy in your own words, and list the variables or conditions that you must consider when comparing the entropy of two substances, or when trying to determine the relative change in entropy. This film covers the juno mission; Entropy is a state function that is often erroneously referred to as the 'state of disorder' of a system.

Minimum enthalpy favours (reactants/products) maximum entropy favours (reactants/products) spontaneous. Qualitatively, entropy is simply a measure how much the energy of atoms and molecules become more spread out in a process and can be defined in terms of statistical probabilities of a system or in terms of the other thermodynamic quantities. We can expect the entropy of the surroundings to increase when water freezes because the heat released stirs up the thermal motion of the atoms in the surroundings.
