Homework Help: physics

Posted by olive on Tuesday, May 4, 2010 at 9:12pm.

How long would it take a 1 200 W heater to melt 1.00 kg of ice at -12.0C, assuming all the energy from the heater is absorbed by the ice? (Assume the specific heat of the ice is 2 090 J/kg C and the latent heat of fusion of water is 3.33 105 J/kg.)

what formula do you use, the fact it asks for time, throws me off
