Chapter 1, Problem 17P

A 15-cm-diameter aluminum ball is to be heated form ${80}^{\circ }\text{C}$ and to an average temperature of ${200}^{\circ }\text{C}\text{.}$ and Taking the average density and specific heat of aluminum in this temperature range to be $p=2700kg/m^3$ and $cp=0.90\text{ kj/kg}\text{.K,}$ respectively, determine the amount of energy that needs to be transferred to the aluminum ball.
