Homework Help: Physics: Capacitance of Capacitor

Posted by Phil-- HELP NEEDED ASAP on Friday, May 10, 2013 at 2:37pm.

Capacitor A and capacitor B both have the same voltage across their plates. However, the energy of capacitor A can melt m kilograms of ice at 0 °C, while the energy of capacitor B can boil away the same amount of water at 100 °C. The capacitance of capacitor A is 8.4 μF. What is the capacitance of capacitor B?

Please note that for water, the latent heat of fusion is Lf = 33.5 x 104 J/kg, and the latent heat of vaporization is Lv = 22.6 x 105 J/kg
