Problem 1 A completely reversible heat engine operates with a source at 2000 R and a sink at 700 R. If the entropy of the sink increases by 15 Btu/R, how much will the entropy of the source decrease? How much heat, in Btu, is transferred from the source? Problem 2 Heat in the amount of 150 kJ is transferred directly from a hot reservoir at 1000 K to a cold reservoir at 500 K. Calculate the entropy change of the two reservoirs and determine if the increase of entropy principle is satisfied.

Question
Please help me solve these 2 problems for my homework
Problem 1
A completely reversible heat engine operates with a source at 2000 R and a sink at 700 R. If the entropy of
the sink increases by 15 Btu/R, how much will the entropy of the source decrease? How much heat, in Btu,
is transferred from the source?
Problem 2
Heat in the amount of 150 kJ is transferred directly from a hot reservoir at 1000 K to a cold reservoir at 500
K. Calculate the entropy change of the two reservoirs and determine if the increase of entropy principle is
satisfied.
