Heat is generated at a steady rate of 100 W due to resistance heating in a long wire (length =5 m, diameter =2 mm). This wire is wrapped with an insulation of thickness 1 mm that has a thermal conductivity of 0.1 W/m.K. The insulated wire is exposed to air at 30°C. The convective heat transfer between the wire and surrounding air is characterized by a heat transfer coefficient of 10 W/m2.°C. The temperature (in °C) at the interface between the wire and the insulation is
