During adiabatic, internally revesivle process, what is true about the change in entropy?
it is temperature dependent
it is always greater than zero
it is always zero
it is always less than zero
What is the difference between adiabatic process and isentropic process?
Adiabatic: heat transfer is not equal to zero
Isentropic: heat transfer is zero
Both: heat transfer = 0
Isentropic : reversible
Both: heat transfer is not equal to zero
Isentropic: irreversible
Adiabatic: heat transfer = 0
Isentropic: heat transfer not equal to zero
