A 3 cm thick slab aluminium (initially at 50°C) is slapped tightly against a 5 cm slab of copper (initially at 20°C). The out-sides are both insulated and the contact resistance is neglible. What is the initial interfacial temperature? Estimate how long the interface will keep its initial temperature.
