A gasoline engine has a power output of 170 kW (about 2.28×105 hp ). Its thermal efficiency is 22.0 %. How much heat must be supplied to the engine per second? Express your answer in joules per second. How much heat is discarded by the engine per second? Express your answer in joules per second.
Air conditioners sold in the United States are given a seasonal energy-efficiency ratio (SEER) rating that consumers can use to compare different models. A SEER rating is the ratio of heat pumped to energy input, similar to a COP but using English units, so a higher SEER rating means a more efficient model. You can determine the COP of an air conditioner by dividing the SEER rating by 3.4.
For inside temperature 24 ∘C and outside temperature 35 ∘C when you'd be using air conditioning, estimate the theoretical maximum SEER rating of an air conditioner. (New air conditioners must have a SEER rating that exceeds 13, quite a bit less than the theoretical maximum, but there are practical issues that reduce efficiency.)

of Aluminum from ( 15 c °) to ( 25 c °) the specific heat of Aluminum (900 J/kg. c°).
