Why the cup at room temperature before the hot cup?
A cup of hot coffee loses more heat to warm a cup. Why cup at room temperature before the warm cup?
It does not work. Look at it this way. As the cup cools hot at a time gave it reaches the temperature of the hot cup was. It takes a certain time interval, which call k. So if the hot cup was taken for X seconds cool the room, then the cup is hot X + k where k is a positive number. + K> X X
