Latent heat question:

Your car's windshield is covered with a .58 cm thick layer of ice. The ice has an area of 1.6m^2. If the temperature of the ice is -2C, how much heat is required to melt all the ice?

heatrequired=massice*specificheatice*(0-(-2))+ massice*latentheat

ok, massice= densityice*volumeice. I would use the density of ice about .932g/cm^2, Volume ice= .58cm*1.6m^2*10^4cm^2/m^2

and you have to look up the specific heat of ice, it is about half that of water, as I recall. Look it up.

To find the amount of heat required to melt all the ice on the car's windshield, you will need to know the latent heat of fusion for ice. The latent heat of fusion is the amount of heat energy required to convert a substance from its solid phase to its liquid phase without changing its temperature.

The equation to calculate the heat required to melt the ice is:

Q = m * L

Where:
Q is the heat required (in joules),
m is the mass of the ice (in kilograms), and
L is the latent heat of fusion for ice (in joules per kilogram).

First, find the mass of the ice:

The volume of the ice can be calculated using the formula:

V = A * h

Where:
V is the volume of ice (in cubic meters),
A is the area of the ice (in square meters), and
h is the thickness of the ice layer (in meters).

Substituting the given values:

A = 1.6 m^2
h = 0.58 cm = 0.58 * 10^-2 m

V = (1.6 m^2) * (0.58 * 10^-2 m) = 0.0928 m^3

Next, find the mass of the ice using its volume and density:

The density of ice is approximately 917 kg/m^3.

m = density * V

m = 917 kg/m^3 * 0.0928 m^3 = 85.0272 kg

Now, you need to know the latent heat of fusion for ice, which is 334,000 J/kg.

Finally, substitute the values into the equation:

Q = m * L
Q = (85.0272 kg) * (334,000 J/kg)
Q ≈ 28,406,464 J

Therefore, approximately 28,406,464 joules of heat are required to melt all the ice on the car's windshield.
