A certain gas with One kilogram of mass, 100 kPa and 45°C is compressed adiabatically until the volume is minimizes to one sixteenth of its original rate. So, heat is further at persistent pressure until the temperature is 1450 °C. The gas is then extended adiabatically till to its initial volume is got and lastly it is cooled at constant volume till the original state of 100 kPa and 1450 °C is reached. Calculate the work done, internal energy and heat transferred for each process. [Take y = 1.4, Cp = 1.004 kJ/kg.K]
