Would you be willing to financially back an inventor who is marketing a device that she claims has 25 kJ of heat transfer at 600o K, has heat transfer to the environment at 300o K, and does 12 kJ of work? Explain your answer.
Suppose a woman does 450 J of work and 9300 J of heat transfer occurs into the environment in the process.
(a) What is the decrease in her internal energy (in kcal), assuming no change in temperature or consumption of food? (That is, there is no other energy transfer.)
(b) What is her efficiency (in percent)?
This problem compares the energy output and heat transfer to the environment by two different types of nuclear power stations-one with the normal efficiency of 32.16N%, and
another with an improved efficiency of 43.521%). Suppose both have the same heat transfer into the engine in one day, 3.29 x 1014J.
a) How much more electrical energy is produced by the more efficient power station?

b) How much less heat transfer occurs to the environment by the more efficient power station? (One type of more efficient nuclear power station, the gas-cooled reactor, has not been
reliable enough to be economically feasible in spite of its greater efficiency.)
