Question
PartA A piece of copper weighing 300 g is initially at a temperature of 23° C. A piece of copper weighing 300 g is initially at a temperature of 23°C. What is its temperature after absorbing 3.9 kJ of energy? (Figure 1) Express your answer using three significant figures vec Figure 1 of 1> TABLE 7. Values of Specific Heat for a Variety of Materials Submit uest Ans Material c, [J/kg KI Provide Feedback Metals Aluminum Copper Gold Iron (a) Lead Nickel Silver Titanium Tungsten 900 385 129 159 237 523 133Explanation / Answer
given specific heat of copper is 385 J/Kg.K
Weight of copper=300g =0.3kg
given temperature of copper = 23 +273=296 K
recived energy=3.9 KJ
energy= MCp(Tfinal-Tinital)
3.9 = .3*385*(Tfinal - 296)
solve this we find Tfinal =329.78K almost 330k
