Applying the Energy Balance

Shown in Fig. P3.87 is an insulated copper block that receives energy at a rate of 100 W from an embedded resistor. If the block has a volume of 10-3 m3 and an initial temperature of 20°C, how long would it take, in minutes, for the temperature to reach 60°C? Data for copper are provided in Table A-19.
