Q2) A long, bare, thermocouple wire having a diameter of 1.0 mm is attached to a ceramic solid having a density of 2400 kg/m³, specific heat of 650 J/kg - C, and a thermal conductivity of 0.85 W/m - C. The conductivity of the thermocouple wire is 75 W/m - C and it is exposed to an environment with h = 275 W/m² - C and a temperature of 50°C. The convection coefficient to the ceramic is 25 W/m² - °C. The indicates a temperature of 220°C. What is the true temperature of the thermocouple solid?
