A 4.3-lb copper block is heated by passing a direct current through it. If the voltage across the copper is 50 V and the current is 13.5 A, what will be the increase in the temperature of the copper after 17 min? Assume there is no heat loss.
Step-by-Step
T \ increase=\frac{4.3\times 0.092\times 50\times 13.2\times 17\times 60}{1055} \ ºF=258.2 \ ºF
