Even when shut down after a period of normal use, a large commercial nuclear reactor transfers thermal energy at the rate of 150 mw by the radioactive decay of fission products. this heat transfer causes a rapid increase in temperature if the cooling system fails. a) calculate the rate of temperature increase in degrees celsius per second (°c/s) if the mass of the reactor core is 1.60×10^5 kg and it has an average specific heat of 0.3349 kj/kg°c
