1. A rubberized sphere contains carbon dioxide. If the initial radius of the sphere is 15cm: a. How much work is done if the carbon dioxide-filled sphere expanded to five times its original  volume against the pressure at STP? Express your answer in L atm. b. Upon the expansion of the sphere, what is the kinetic energy of a single carbon dioxide  molecule if it travels across the diameter and covers it in 30ms? Assume that the sphere  contains one mole of carbon dioxide. Express your answer in J. c. How much power can all the molecules in this sphere generate after 30s? Assume that the  sphere contains one mole of carbon dioxide and that all molecules have the same kinetic  energy. Express your answer in W. (Use the KE obtained from the previous required)  (Note that 1L atm=101.325J)
