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
Convection can best be observed as she blows the warm steam air that rises. As the warm steam rises, she forces displaces it with cool air from her mouth. Because the warm steam is less dense it rises and because the cool air is more dense, it displaces the warm air. This scenario is an example of convection.
