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

- Relevant 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...?
