## Homework Statement

A woman finds the front windshield of her car covered with ice at -12.8°C. The ice has a thickness of 4.60 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?

## Homework Equations

Q=mL or change temp=Q/constant*mass

## The Attempt at a Solution

:surprised Volume = Area * thickness<<then found the density

Q=mct Energy = mass* specific heat* cahnge in temp

heres the numbers that I plugged in: Q=(917)*(5.75*10^-4)*(12.8)*(22.6*10^5)<this last number is the latent fusion for water

the answer I got was wrong. not sure if I'm make a simple mistake or completely on the wrong track!

thanks in advance
