A woman finds the front windshield of her car covered with ice at -12.6°C. The ice has a thickness of 4.80 10-4 m, and the windshield has an area of 1.25 m2. The density of ice is 917 kg/m3. How much heat is required to melt the ice?

Use the area, thickness, and density to calculate the mass of ice.

Then mass ice x specific heat ice x 12.6 = joules necessary to raise the temperature of the ice to zero degrees C. then add in the amount to melt the ice which is mass ice x heat of fusion. Watch the units. Post your work if you get stuck.
