16. A gas is initially at a pressure of 100 kPa and its volumeis 2-0 m. Its pressure is kept constant and the volumeis changed from 2.0 m3 to 2.5 m3. Its volume is nowkopt constant and the pressure is increased from100 kPa to 200 kPa. The gas is brought back to its initialstate, the pressure varying linearly with its volume. (a)Whether the heat is supplied to or extracted from thegas in the complete cycle? (b) How much heat wassupplied or extracted? |
