Two kittens are sleeping by a furnace vent.They are relying mainly on what kind of heat transfer? A. Chemical heating B. Thermal conduction C. Radiation warming D. Convection heating

## Step 1<br />The problem involves understanding the different types of heat transfer mechanisms. The kittens are sleeping by a furnace vent, which means they are receiving heat from the furnace. The heat is transferred through the air, which is a fluid, and this process is known as convection.<br /><br />## Step 2<br />Convection is a type of heat transfer that occurs in fluids (liquids and gases). It involves the movement of the fluid itself, carrying heat from one place to another. In this case, the air heated by the furnace rises and carries the heat to the kittens.<br /><br />## Step 3<br />The other options, such as chemical heating, thermal conduction, and radiation warming, do not apply in this scenario. Chemical heating involves a chemical reaction to produce heat, which is not the case here. Thermal conduction involves direct contact between objects, which is not the case as the kittens are not in direct contact with the furnace. Radiation warming involves heat transfer through electromagnetic waves, which is not the case here as the kittens are not receiving heat through radiation.
