PLEASE ANSWER QUICK!! Which of the following is an example of heat transmission by convection?
A. The heat from the sun melts a snowman even though it's below freezing
outside.
B. Liquid inside a beaker on a hot Bunsen burner circulates and heats through
constant motion.
C. An iron bar is placed inside a hot furnace and begins to glow orange.
D. A skillet on a very hot stove burner heats up uniformly and quickly.

B. Liquid inside a beaker on a hot Bunsen burner circulates and heats through  constant motion.

Explanation:

As we know that in convection mode of heat transfer the thermal energy is transferred by the actual movement of medium particles

Here we know that the medium particles will move absorb the heat from the heating or energy source and then transfer from one position to other position due to change in the density

This movement of the medium particles will carry the energy along with it and this will help the energy to transfer from one point to other point

So here we know that convection mode of heat transfer is represented by

B. Liquid inside a beaker on a hot Bunsen burner circulates and heats through  constant motion.

hèllo, sorry i really need some more points so if you need this qustion answered than retype it

its a 5.5 n

glad that
