A steam engine’s boiler completely converts
151 kg of water to steam. This process in-
volves the transfer of 4.8786 J J as heat.
If steam escaping through a safety valve
does 1.66 × 108 J of work expanding against
the outside atmosphere, what is the net
change in the internal energy of the water-
steam system?
