Question

1) 2 kg of solid copper is at its melting point. How much energy does it take to melt all the copper?

Heat of fusion: 134 J/g
Heat of Vaporization 5060 J/g

q= mHf


I know the equation but I do not understand know if this is correct.
2kg= 2000 grams
q=(2000g) (134J/g)
q=(2000) (134J)
q=268000J
Correct. Go to the head of the class.
