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 1023 m3 and an initial temperature of 208C, how long would it take, in minutes, for the temperature to reach 608C? Data for copper are provided in Table A-19.
