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)rising steam from the cup of cocoa
d)blowing on the hot cocoa to cool it

Option (C) is the correct answer.

Explanation:

When a fluid is heated then then hot liquid (less dense) rises and cool liquid (more dense) sinks at the bottom and this process is known as convection.

For example, when cocoa mix is poured into milk and heated in an oven then molecules of milk and cocoa inter change their position due to heating and cocoa mixes into the milk.

And steam (less dense) rises at the top and cool cocoa (more dense) sinks at the bottom.

Thus, we can conclude that rising steam from the cup of cocoa is a part of this scenario in which convection can be best observed.
