Yami pours powdered cocoa mix into milk and stirs it. Then she microwaves the mixture for three minutes. When she takes the cup out, the handle is very warm. Steam rises from the cup, so she blows it before taking a sip. In which part of this scenario can convection be best observed?

A. stirring powdered cocoa mix into milk

B. touching the warm handle of the cup

C. touching the warm handle of the cup

D. blowing on the hot cocoa to cool it

Respuesta :

Pretty sure it's D but may be wrong

Answer:

D. blowing on the hot cocoa to cool it is the correct answer.

Explanation:

Convection can be defined, according to the Cambridge Dictionary, as "the flow of heat through a gas or a liquid as the hotter part rises and the cooler part falls." In this case, the hot cocoa is getting cooler as cool air arrives to the hot cocoa and the steam caused by it rises. Due to this, D is the correct answer.
