calculate the amount of heat energy in joules to condense 125g of steam at 100 degrees celcius and cool to the liquid to 15 degrees celcius?
Note the correct spelling of celsius.
q1 = heat released to condense steam at 100 C to liquid at 100 C.
q1 = mass x heat vaporization
q2 = heat released on cooling from 100 C to 15 C.
q2 = mass water s specific heat water x (Tfinal-Tinitial).
Total Q = q1 + q2.
