People sitting around a campfire are able to feel the heat from the fire. How are the people able to feel the heat from the fire without touching the fire?
The heat from the fire travels through the ground and heats the ground around the people.
The heat from the fire is conducted through air molecules to the people.
The heat from the fire rises in the air and then settles around the people.
The heat from the fire radiates from the fire to the people.
