2. A rubberized, cubic chamber was filled with butane gas and was expanded from 3.0L to 4.5L at a

pressure of 2.7atm and it absorbed 230J of heat from the surroundings.

- Assuming that the internal energy of this system is all kinetic energy and that the cube

contains one mole of butane gas, what is the velocity of a single butane molecule covering a

distance between the opposite corners of the expanded cube (express in m)? How long

would it take to cover that distance (express in sec, use SI prefixes instead of scientific

notation)?

- How much power can be generated by all the molecules in this cube after 1 hour? Express

your answer in W. (Use the v obtained from 2b then recompute total KE)
