A 10 foot by 10 foot by 10 foot room contains air at 95 degrees Fahrenheit. In the middle of the room is a tray holding a 10kg block of ice whose temperature is 0 degrees Centigrade. When the ice has completed melted and the remaining water is at room temperature what is the room temperature. Assume that specific heat and density of water are both 1.
