Picture yourself around a campfire. Which of these would be an example of convection?
A metal rod would not be a good choice for roasting marshmallows because metal transfers
thermal energy.
O As the air around the campfire is heated and becomes less dense, it rises and
moves upward.

O As the air around the campfire is heated and becomes less dense, it rises and moves upward.

Explanation:

This is true because, the convection transfer needs the particle of elements to transport the heat from where it is in abundance to where it is in less abundance. Just like a water boiling becoming hot at the point closer to the fire than the top of the pot, so also will the air around campfire transfer heated air from the place closer to the campfire to upwards aware from the fire.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.yes it's true.
