Question 1 A convective heat transferilis a: heat transfer at a molecular level P Flag question heat exchange between two fluids through a separating wall heat transfer by electromagnetic waves heat exchange between the wall and the fluid washing over it

The correct answer is: heat exchange between the wall and the fluid washing over it.<br /><br />Convective heat transfer refers to the transfer of heat by the movement of a fluid (liquid or gas) over a surface. It occurs when there is a temperature difference between the fluid and the surface, causing the fluid to move and carry heat away from the surface. This type of heat transfer is different from conduction (heat transfer at a molecular level) and radiation (heat transfer by electromagnetic waves).
