a hot reservoir at 576k transfers 2100 j of heat irreversibly to a cold reservoir at 350 k. Find change in entropy of the universe.

Expert Solution

Given Q = 2100 J

T = 576 K

T ' = 350 K

Change in entropy of the universe dS = (Q /T ' ) -(Q/T)

= (2100 /350 ) -( 2100 /576 )

= 6 - 3.6458

= 2.354 J/K

A piece of equipment functions such that a hot reservoir at 605 K transfers 1150 J of heat irreversibly to a cold reservoir at a temperature of 296 K. 1) What is the change in entropy of the hot reservoir? ΔSH = J/K 2) What is the change in entropy of the cold reservoir? ΔSc = J/K 3) What is the change in entropy of the whole universe due to this process? ΔS = J/K

Consider three engines that each use 2160 J of heat from a hot reservoir (temperature = 540 K). These three engines reject heat to a cold reservoir (temperature = 335 K). Engine I rejects 1497 J of heat. Engine II rejects 655 J of heat. Engine III rejects 1340 J of heat. One of the engines operates reversibly, and two operate irreversibly. However, of the two irreversible engines, one violates the second law of thermodynamics and could not exist. For...
