. Consider two systems,1and 2,interacting thermally but not mechanically or diffusively. Their initial temperatures are 0 ◦C and 50 ◦C, respectively. The heatcapacitiesofsystem1areCV1 =2R,Cp1 =2.8R,andthoseofsystem2 areCV2 =3R,Cp2 =4R; R, the gas constant=8.31 J/(K mole). Find (a) their temperature after reaching equilibrium, (b) the change in entropy of system 1, (c) The change in entropy of the total combined system. (d) Why is one of the heat capacities (CV orCp) irrelevant here?

1 mole of a gas undergoes a mechanically reversible isothermal expansion from an initial volume 1 liter to a final volume 10 liter at 25oC. In the process, 2.3 kJ of heat is absorbed in the system from the surrounding. The gas follows the following formula: V=RTP+b where V is the molar specific volume, and Tand Pare temperature (abosolute) and gas pressure respectively. Given R= 8.314 J/(mol.K) and b= 0.0005 m3. Evaluate the following a) Work (include sign) b) Change...

Consider two bodies with temperature independent heat capacities C1 and C2, and initial temperatures T1 > T2. (a) If the two bodies are brought into contact such that the only heat exchange is between them, what is the final temperature Tfinal , and what is the change in entropy. (b) Suppose instead that the difference in temperature between the two bodies is used to drive an ideal heat engine (Carnot cycle). In one operation of the cycle some amount of...

Consider two blocks. The initial temperature of block 1 is 280 K and the initial temperature of block 2 is 340 K. The heat capacities of blocks 1 and 2 are 400 J/K and 200 J/K, respectively. A. The two blocks are placed in thermal contact with one another but are perfectly insulated from the remainder of their surroundings. We will call the process that begins when the blocks are brought in contact with one another process A. Determine the...

It is possible to go from a given initial equilibrium state of a system to a given final equilibrium state by a number of different paths, involving different intermediate states and different amounts of heat and work. Since the internal energy of a system is a state function, its change between any two states must be independent of the path chosen. The heat and work flows are, however, path-dependent quantities and can differ on different paths between given initial and...
