A piston-cylinder device initially contains CO2 at 200 kPa and 400°C and the total enclosed volume is 300 litres. Due to heat loss, the piston moves downwards to a position where it sits on a pair of stoppers and its final enclosed volume is 150 litres. Further heat loss leads to the pressure being reduced to 160kPa. Workout 1) the final temperature, 2) the total work done by CO2 and 3) the total heat transferred to CO2. Also make some comments on the result of heat. 4) Create a schematic p-v diagram of the process The following assumptions are to be made: CO2 is a perfect gas and its molecular mass is 44kg/kmol. The ratio of specific heat capacities, γ (gamma) is 1.3 The volume occupied by the stoppers is to be ignored. There is no leakage in the system There is no friction between the cylinder and piston walls and the piston moved slowly at the same speed therefore, no acceleration.

The kitchen, bath, and other ventilation fans in a house should be used sparingly since these fans can discharge a houseful of warmed or cooled air in just one hour. Consider a 200-m2 house whose ceiling height is 2.8 m. The house is heated by a 96 percent efficient gas heater and is maintained at 22°C and 92 kPa. If the unit cost of natural gas is $1.20/therm (1 therm = 105,500 kJ), determine the cost of energy “vented out” by the fans in 1 h. Assume the average outdoor temperature during the heating season to be 5°C.
