A rectangular plate m by 2.5m and thickness of 4mm is heated by a resistance wire from one side and is exposed to the atmosphere (with a convective heat transfer coefficient of 20W/m2.°C) on the other side. The plate is made of aluminum (check for the properties online and quote your source) The power input to the resistance wire is 1kW. If the plate is initially in thermal equilibrium with the atmosphere at 20°C, calculate the temperature of the plate after 2 minutes. Clearly state all assumptions made. You must derive the relevant equations from the basic conservation of energy principle.
