Question

which is an example of forced convection? burning your tongue on the hot tea hot tea warming the cup it is in blowing on the hot tea to cool it off

Explanation:

Forced convection is a type of heat transfer where fluid motion is caused by external means (like blowing air). Burning tongue is conduction (direct heat transfer). Hot tea warming cup is also conduction. Blowing on tea uses external air movement (blowing) to enhance heat transfer (cooling), which fits forced convection.

Answer:

Blowing on the hot tea to cool it off
