One mole of ideal gas, initially at 50OC and 1 bar, is changed to 150oC and 4bar by 2 different mechanically reversible processes as follows:
process 1: the gas is first heated at constant pressure until its temperature is 150oC and then it is compressed isothermally to 4 bar
process 2:the gas is first compressed adiabatically to 4bar and then it is cooled at constant pressure to 150OC
i)Assume Cv =2.5R and Cp=3.5R, estimate the heat(J) and work(J) for both processes
ii)Select the most energy efficient process.Justify your answer.

A 500 mL water sample was analyzed for solids concentrations. The sample was filtered through an ash-free 1.5 µm filter paper having a tare weight of 1.115 g. After drying at 105 °C for 24 h, the filter paper weighed 1.552 g. The filter paper was then placed in a crucible having a tare weight of 32.216 g and which was then placed in an ashing oven at 550 °C for 24 h. After cooling, the crucible weighed 32.521 g. A subsample consisting of 50 mL of the filtrate was placed in a crucible having a tare weight of 41.814 g. After drying (105 C for 24 hr), the crucible weighed 41.828 g, and after ashing (550 C for 24 hr) it weighed 41.820 g.
Required: Determine the following concentrations in mg/L: a. Total suspended solids (TSS) b. Fixed suspended solids (FSS) c. Volatile suspended solids (VSS) d. Total dissolved solids (TDS) e. Fixed dissolved solids (FDS) f. Volatile dissolved solids (VDS) g. Total solids (TS) h. Total volatile solids (TVS) i. Total fixed solids (TFS)
