Answer each of the following questions by writing all applicable equations and information, showing all work, and circling the final answer with appropriate significant figures and units. Part 1: Heat, Work, and Internal Energy 1. Show how the equation for work done on or by a gas is dependent on pressure and change in volume. 2. What are the two ways energy can be transferred to or from a substance? Be specific, and justify your answers. 3. An air mixture of gasoline and vapor is placed in an engine cylinder. The piston has an area of 9.40 x 10-2 m2 and the displacement is 7.2 x 10-2 m. If 1.25 x 106 Pa of pressure is placed on the piston, how much work is done during this process? Is work being done on or by the gas mixture? 4. A balloon is inflated with Helium at a constant pressure of 4.30 x 103 Pa. If the balloon requires 3.31 J to inflate from a volume of 1.80 x 10-4 m3, what is the final volume of the balloon
