C. An expeiment was conducted on block of copper material.In this experiment a copper block of 800 grams of mass with a heat capacity of 0.15 kJ/K at 98 oC is dipped in river at 9 oC.In the second step the same copper black at 98 oC dropped into the river from a height of 120 m.After the two process both the copper blocks at 98oC and 0oC both are combined together.Calculate the total entropy change for the each of the process.

Consider an isolated system containing two blocks of copper with equal mass. One block is initially at 0oC while the other is at 100oC.They are brought into contact with each other and allowed to thermally equilibrate. What is the entropy change for the system during this process? The heat capacity for copper is Cp = 24.5 [J/mol k]

A 50 kg copper block initially at 350 oC is quenched in a closed, rigid insulated tank containing 120 L of liquid water at 25 oC. Specific heat of copper, Cc = 385 J/(kgK), specific heat of liquid water, Cw = 4180J/(kgK). (i) Calculate the entropy change (kJ/K) of copper block. (ii) Determine the entropy change (kJ/K) of liquid water.

A block of copper has a mass of 100 kg and an initial temperature of 900 K. Copper can be modeled as an incompressible substance with a specific heat capacity of 0.4 kJ/kg-K. a.) The copper block is dropped into a large lake at 300 K and allowed to come to thermal equilibrium. How much entropy is generated (kJ/K)? b.) If a reversible heat engine were connected between the lake and the copper block and operated until the temperature of...

A 59-kg iron block and a 20-kg copper block, both initially at 80°C, are dropped into a large lake at 15°C. Thermal equilibrium is established after a while as a result of heat transfer between the blocks and the lake water. Assuming the surroundings to be at 20°C, determine the amount of work that could have been produced if the entire process were executed in a reversible manner. The specific heats of iron and copper are 0.45 kJ/kg·K and 0.386...
