Q1. A plot of pressure as a function of volume is known as a pV diagram. pV diagrams are often used in analyzing thermodynamic processes. Consider an ideal gas that starts in state O, as indicated in the diagram. Your task is to explain how the gas proceeds to one of four different states, along different curves indicated.
Q2. A 95.0 kg fullback moving south with a speed of 5.0 m/s has a perfectly inelastic collision with a 92.0 kg opponent running directly at him with a speed of 3 m/s. Calculate the decrease in total energy therefore of this collision.
