Calculate Heat for Melting 10kg Ice Block

[strawberry7]

Homework Statement

Calculate the amount of heat energy required to melt a 10 Kg block of ice at 0 degrees C into liquid water at 0 degrees C. The latent heat of fusion for water is 3.34 * 10to the 5

Homework Equations

Q = mc(change in temperature)

The Attempt at a Solution

Q = (10)(3.34 * 10to the 5)(0)
Q= 0

That is not the equation for thermal energy involving latent heat of fusion.

that is exactly what the question said...Actualy therre is a typo I'll edit it

The ice is undergoing a phase change here (from ice at 0 degrees to water at 0 degrees). In this situation, there is no change in temperature even though thermal energy is being generated. The equation you are using is not the one you need for this. You need Q=mL, where m is the mass of the ice, and L is the latent heat (of fusion in this case). Look it up.

thankyou!
