Thermodynamics: Finding Specific Heat of Ice

[swede5670]

Homework Statement

It takes 15 seconds to warm ice 15 degrees ( -15 degrees celsius to 0 degrees celsius). The ice has a mass of .25 kg. The energy is supplied at 530 W to the ice.

Homework Equations

Q = mc delta T

The Attempt at a Solution

I plugged in all the information for Q
(15 seconds * 530 W) = .25 * c * 15 degrees
which ends up with c = 2120

Did I do this correctly
