Posted by J.M. on Saturday, September 23, 2006 at 3:07pm.

A 500kg steel boiler is used to convert 200kg of water into steam. Calculate the total energy required to heat both the steel and its' contents from 20.0C to 100.0C. The specific heat capacity of the steel is 0.528J/gC.


Heattotal= heat steel + heat water + heatsteam

= masssteel*Cs*(Tf-Ti) + mw*cw*(tf-ti)+ mw*Lv where Lv is the latent heat of vaporization for water
