y feel cooler to the touch than the other. Consider thick plates of copper and glass, each at an initial temperature of 301 K. Assume your finger to be at an initial temperature of 310 K and to have thermophysical properties of 1000 kg/m3, 4180 J/kg·K, and 0.625 W/m·K. What is the specific heat of copper at 300 K (use this temperature for the analysis), in J/kg·K?
