Physical chemists tell us that a typical chemical bond has a force constant in the range of k = 500 Nm. Assume that we have a spring with the same force constant, and that a 1.00 pound weight is attached. How far will the spring stretch? (Hint: need to introduce acceleration due to gravity and balance downward and upward forces)

10 kg of co2 is initially contained at 400 kpa and 300 k. the gas constant for carbon dioxide is 189 j/lkg k) and has a specific heat ratio, k, of 1.289. isentropic expansion then occurs until the pressure is 200 kpa. a) determine the initial volume of co2 in m. b) determine the final temperature in k. c) determine the work done by the system during the expansion kl.
