Hi, can you please help me with these two questions? I would like to understand what is happening through the schematics first before moving on to the substantive equations. Internal combustion engines (ICE) use pistons and cylinders to derive power from a working fluid,generally a mixture of fuel and air, undergoing a thermodynamic cycle. Though real ICEs are open systems,it is often convenient to model ICEs by approximating the piston-cylinder assembly as a closed system thatis operating with air. In an ICE, like in the Carnot cycle heat engine, the working fluid undergoes a seriesof processes before returning to its initial state. We will spend significant time studying these cycles intheir entirety in Chapter 10. Here, you will focus only on one of the processes of an idealized ICE cycle: anadiabatic and reversible compression process.Consider an ICE engine modeled with air as the working fluid. The process of interest is an adiabatic andreversible compression. The compression process starts at 300 K and 100 kPa and the air is compresseduntil its volume is one-tenth of its original volume.Please answer the following after creating a schematic for the piston cylinder device associated with thiscompression process in the engine and a sketch of the process on P-v and T-s diagrams. Do not includevalues on the axes, just symbols using subscripts 1 and 2 to denote the initial and final states.a) Using the method of constant specific heats with the specific heat value that corresponds to thetemperature of the start of the compression process (also known as the cold-air standard analysis)determine:İ. The pressure and temperature at the end of the compression process.ii.The work per unit mass required for the compression.b) Using the method of variable specific heats determine:İ.ii.The pressure and temperature at the end of the compression process.The work per unit mass required for the compression.

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
