In a reversible process entropy of the system
WebMay 22, 2024 · During irreversible process the entropy of the system increases. There are many factors that make a process irreversible: Presence of friction and heat losses. In real thermodynamic systems or in real heat processes, we cannot exclude the presence of mechanical friction or heat losses. Finite temperature difference. WebFinally DS Sur = -DS Sys because the process is reversible and therefore the total entropy change must be zero. 5) 0.200 moles of an ideal gas initially at 30 C and in 1 liter is expanded to a final volume of 2 liters and cooled to a final temperature of 10 C. Assume that the molar C V = (3/2) R.
