A working substance absorbs 200 J of energy from a reservoir at 400K and also 300 J from
a reservoir at 300 K. It interacts with a third reservoir whosetemperature is T3 . When the
system returns to its original state, it has done net work in theamount of 100 J.


1. What is the entropy change of the working substance for thecomplete cycle?

2. What is the numerical value of the temperature T3 ?

During a liquid-to-solid phase change of a substance, its changein entropy is -4.60 x 103 J/K. If 1.16 x 106J of heat is removed in the process, what is the freezing point ofthe substance?

Answer in degrees Celsius
