Calculate the amount of energy (in kj) necessary to convert 277 g of liquid water from 0°c to water vapor at 167°c. the molar heat of vaporization (hvap) of water is 40.79 kj/mol. the specific heat for water is 4.184 j/g · °c, and for steam is 1.99 j/g · °c. (assume that the specific heat values do not change over the range of temperatures in the problem.)

Avehicle has an oil leak that is causing the entire oil pan to be wet, but inspection reveals no exact source after cleaning off the oil residue. technician a says to install a fluorescent dye in the crankcase and operate the engine, then re-inspect for leaks with a special light (black light). technician b says the oil leak may be coming from a source at the top of the engine, such as a valve cover gasket. who is correct?
