An ethnic restaurant serves coffee in copper mugs ( c=390 J/kg Co ) ( unit is read as: Joule per kilogram.Celsius degree ) . A waiter fills a mug having a mass of 0.100 kg initially at 20.0 degrees Celsius with 0.200kg of coffee initially at 70.0 degrees Celsius. If the final temperature at which the coffee and mug reaches thermal equilibrium is 67.8 degrees Celsius, how much heat was added to the mug?
