Product Description : Size: Photo MugPhoto Mug showing Entropy shown by heat loss. Entropy shown by heat loss. Entropy is a measure of the amount of order or disorder in a system, as well as how reversible a change is. This is illustrated here by the hot tea (left) losing heat to become a colder cup of tea (right), a process that can only be reversed by adding energy. The tea s energy being dissipated is due to entropy increasing (the second law of thermodynamics). Eventually,
