A 0.5 m3 rigid tank contains R-134a initially at 200 kPa and 40% quality. Heat is transferred to the refrigerant from a source at 35oC until the pressure rises to 400 kPa. Determine…
a.) The entropy change of the R-134a.
b.) The entropy change of the heat source.
c.)The entropy change of the universe for this process.

Is the entropy change of the universe equal to the entropy change of R-134a + entropy change of the source?
Yes.
