Question

Which word is defined by this statement: A measure of this disorder, or randomness? a. energy b) entropy c. enthalpy d. mass In which of the following does entropy not remain constant a. Reversible adiabatic process b. Isentropic Process c. Internally reversible process d. Constant-pressure heating in a real boiler The second law of thermodynamics states that entropy can be created but it cannot be destroyed. Therefore a. Delta S_system = 0 b. Delta S_system greaterthanorequalto 0 c. Delta S_system lessthanorequalto 0 d. Delta S_system

Explanation / Answer

1)entropy which is degree of randomness.

2)d

3)b, i.e it can never be negative and ought to some randomness.

4) S = Q/T

=2000 KJ/550 k

=3.636 KJ/k

So correct choice is a.

5)b, isentropic turbines
