Agoldsmith melts 12.4 grams of gold to make a ring. the temperature of the gold rises from 26°c to 1064°c, and then the gold melts completely. if gold’s specific heat is 0.1291 joules/gram degree celsius and its heat of fusion is 63.5 joules/gram, how much energy is gained by the gold? the gold gains a total of joules of energy. i was given this by somebody. no idea what to do with this. qj=(12.4g(1064-26)°c0.1291j/g/°c) +(12.4g*63.5j)
