 Homework Statement
 Power generated is the work done per unit time. Also latent heat of ice is 80cal.
 Homework Equations

P=W/t
W= Energy = heat generated ?
Heat Q= mass x latent heat
P=W/t
W=Q= mL = (100x 80x 4.2)/1000 (kg x J/kg)
= 33.6
t= 1 minute= 60s
P= 33.6/60= 0.56 watt...
but the answer provided is 560J/s...???
