- how does a penguin use
this to keep warm?
-

Since the outer plumage of the penguin can resist the flow of heat in the cold antarctic air they might gain a little of this heat to keep them warm by thermal convection.

Explanation:

Convection is the circular movement that happens when hot air/liquid moves with molecules that were fast, making it less dense rises while the cold air/liquid drops down.Also, they follow the technique of standing together always in a group which further helps them to decrease the loss of heat between them.The plumage of penguin provides 80 percent of total insulation and is highly resistant to wind penetration.

Iwould sure like to answer your question but i honestly just don’t know
