(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

the latent heat of fusion for this metal is 500Cal/kg. The latent heat of vaporization is 600Cal/kg and specific heat of the liquid metal is 500C/kg K. How much heat is needed to melt an 8kg block of this metal when its temperature is exactly at the melting point?

2. Relevant equations

T= kelvins

c=specific heat

Q is heat needed

Q= m*c*delta T

Q=m*Latent heat (either fusion or vapor)

3. The attempt at a solution

Q= 8 * 500Cal/kg

Will someone please sho wme how to do this>?
