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!
