Copper heat capacity would be <span>0.385J/C*gram which means it needs 0.385 Joule of energy to increase 1 gram of copper temperature by 1 Celcius. The calculation would be: energy= heat capacity *mass * temperature difference energy= </span>0.385J/C*gram * 6g * (90-20) <span>energy= 161.7J </span>
