Mug lose through conduction than from radiated energy

Reference no: EM13549952

As a coffee enthusiast you wish to keep your coffee as hot as possible for as long as possible. You wish to find the rate of heat loss of a typical coffee mug. Assume the mug to be a cylinder which has a lid made out of the same material as the rest of the cylinder, and the thickness of the walls is 1.34 cm. If the coffee in the mug is 75.0 °C and the room temperature is 20.0 °C how much more heat does the mug lose through conduction than from radiated energy.
