WebEither of Equation ( 6.5) or ( 6.6) can be interpreted to mean that the entropy of the system, , is affected by two factors: the flow of heat and the appearance of additional entropy, denoted by , due to irreversibility 6.1. This additional entropy is zero when the process is reversible and always positive when the process is irreversible. http://web.mit.edu/16.unified/www/FALL/thermodynamics/notes/node41.html

The first law of thermodynamics states that the change in internal energy of a system is equal to the difference of the heat added to the system and the work done by the system. In equation form, this is: \Delta E=Q-W ΔE = Q− W. Where E is the internal energy, Q is the heat …

WebThe total entropy change is. Figure 5.5: Work from a single heat reservoir. The total entropy change in the proposed process is thus less than zero, which is not possible. The second law thus tells us that we cannot get work from a single reservoir only. The ``only'' is important; it means without any other changes occurring. WebAdding heat flow to the law of conservation of energy gives the first law of thermodynamics. "When heat flows to or from a system, the system gains or loses an amount of energy …

WebThis is in contrast to work that is positive when energy is transferred from the system and negative when transferred to the system. The symbol q is sometimes used to indicate the heat added to or removed from a system per unit mass. It equals the total heat (Q) added or removed divided by the mass (m).
