The rate of entropy transfer associated with heat transfer from a closed system operating at steady state to its surroundings must be equal to the rate of entropy production due to irreversibilities within the system. O True O False eTextbook and Media Save for Later
Derive an expression for the change in entropy of the universe. 7
When two systems are in contact, the entropy transfer from the warmer system is equal to the entropy transfer into the cooler one at the point of contact. That is, no entropy can be created or destroyed at the boundary since the boundary has no thickness and occupies no volume.
If the entropy change of an adiabatic, closed system process is positive, the process is which of the following? Impossible, irreversible, externally reversible, internally reversible?
answer the following true or false. (a) A process that violates the second law of thermodynamics violates the first law of thermodynamics. (b) When a net amount of work is done on a closed system undergoing an internally reversible process, a net heat transfer of energy from the system also occurs. (c) A closed system can experience an increase in entropy only when a net amount of entropy is transferred into the system. (d) The change in entropy of a closed system is the same for every process between two specified end states.
