Entropy is basically the measure of “disorder” in a system. It increases with every action and reaction. Entropy may be generated (or created), but it cannot be destroyed. Temperature and entropy are somewhat proportional. Entropy is measured in .
Example: A man running on a day with temperature of 32°C and he loses 2.5 kg of perspiration. In this case, the latent heat of vaporization for perspiration is . Estimate the change in entropy of the water in order to vaporize the water.
