Answer:
Draw a Fire heating a cup of water on a metal grate. Draw circles made of arrows inside the water. Draw wiggly metal lines on the metal grate along the metal bars. Draw dashed lines leaving the fire in all directions.
Explanation:
Convection is when fluids move due to difference in temperature, this is shown by the arrows in the water. Conduction is when heat is transferred between two objects touching, this is shown by the arrows on the metal grate. Radiation is when heat is transferred by light, this is shown by the dashed lines leaving the fire in all directions.
