A company is developing a project for a thermal engine that uses air as the working substance. At a certain stage of the cycle, the air is at a pressure of 2 atm and a volume of 0.05 m³, and undergoes an isothermal compression process until reaching the final volume of 0.03 m³. Considering that the air behaves as an ideal gas and that the temperature remains constant during the process, answer the following items: a) What is the final pressure of the air after compression? b) Calculate the work done on the air during compression. c) Based on the information obtained, describe the implications of increasing or decreasing the final volume in the isothermal process and how this can affect the efficiency of the thermal engine.
