Heat is generated (given edot) uniformly in a spherical radioactive object that is subject convection conditions (a given fluid h and steady Tamb) on the outside surface. Determine the correct form of the heat conduction equation, the temperature distribution, and the rate of heat transfer.

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.
