Which is a type of heat transfer that causes the air at the top floor of a building to be hotter than the air at the bottom floor of a building? conduction convection radiation reflection

convection

Explanation:

Convection is the transfer of heat from one place to another by movement it is one to another forms of convection as radiation. Conversion involves the transfer of heat to liquids in convection, namely gases and liquids. Transfer through convection is enhanced by convection flows. Convection currents are circular paths through which the warm lighter fluid moves up and the denser cold fluid moves downwards. This increases the heat exchanger between the hot fluid and the cold fluid as a result of the temperature difference. Therefore, convection type convection explains why the air on the top floor of the building is hotter than the air on the building floor.
