Thermodynamics - Assignment ExampleThe idea of making a bag that would maintenance the pizza hot for as long as it remains in it is reinforced on the possibility of creating an isolated system. Once an isolated system is created, the first police force guarantees that the energy (heat is a form of energy) pass on remain constant inside the system, which means whatever is in the bag will have a constant temperature, since temperature is a measure of heat.A nonher way to phrase the first law of thermodynamics is energy can neither be created nor destroyed, given that the isolated system is one that does not furnish energy nor matter to cross its boundary it is easy to see how an isolated system can keep its temperature constant.Another way to put it is that energys ability to do operation always decreases. In terms of heat, work is done by heats transition, and so for the energys ability to do work to decrease (i.e. for entropy to increase) the systems would reach their uttermost entropy when they have the same temperature, which would mean that they will no longer be able to transform heat between them and therefore would not be able to do work.As isolated systems, the pizza bags entropy increases, however the pizza bag and the surroundings together have an entropy that does not increase, this does not violate the second law of thermodynamics since it states that only entropy of an isolated system can increas
