Entropy is a measure of the degree of randomness of the molecules comprising the system. Higher the disorder, greater is the increase in entropy. Entropy is the function of a quantity of heat which shows the possibility of conversion of that heat into work. The ...
The second law of thermodynamics can also be stated using Clausius, Kelvin and Planck statements also. Each statement is based on an irreversible process. The Clausius and the Kelvin and Planck statements of the second law of Thermodynamics are given below: Clausius statement: Clausius statement states “it is ...
Maximum efficiency of an engine working between temperatures T2 and T1 is given by the fraction of the heat absorbed by an engine which can be converted into work is known as efficiency of the heat engine. Mathematically, In First case: Efficiency, η = (T2 - T1) ...
Change in entropy during constant volume process is given as: = m cv ln (T2 / T1) Change in entropy during polytropic process i.e. (PVn = constant) = m cv [(γ – n)/ (n – 1)] ln (T2 / T1) For the same entropy, equating both the above equations, ...
