Hot coffee is stirred with a spoon, the spoon gets hot due to:
a. conduction
b. convection
c. radiation


Sagot :

B. Convection As far as I remember, it is the answer because when you say convection, it is the heat being transferred to a solid by a liquid. The given says hot coffee and the spoon gets hot. Obviously the hot coffee is a liquid and so it is hot which means it has heat. So while the spoon is in the hot coffee, the heat is being transferred to the spoon. So it is therefore convection. Hope this helps. :)
Conduction is my final answer.
