A chemist wants to calculate the amount of heat that is absorbed by a sample of copper as it is melted. Which constant should she use?

Respuesta :

She needs to use the heat of fusion (ΔH(fusion)) and the equation q=mΔH(fusion) or q=nΔH(fusion)  depending on whether or not ΔH(fusion) is given in J/g or J/mol.  The reason why temperature is absent from the equation is that temperature does not change at a phase change, only the enthalpy does.

I hope his helps.  Let me know in the comments if anything is unclear.
