For each of these heat transfer processes: (i) calculate how much the entropy of the system changes. (ii) calculate how much the entropy of the environment changes. (iii) is this process irreversible, reversible, or impossible? except where specified (part d) all processes occur at constant temperature. a. 50 joules of heat is transferred from a system at 100 °c to a reservoir at 5 °c b. 50 joules of heat is transferred from a system at 5 °c to a reservoir at 100 °c c. 50 joules of heat is transferred from a system at 5 °c to a reservoir at 5 °c d. 50 joules of heat is transferred to a reservoir at 5 °c. during this heat transfer process, the temperature of the system changes from 15 °c to 5 °c so that dt = 2 8q
