Which of the following processes does not occur during the convective transfer of heat within a container of air? group of answer choices the cooler portion of the air surrounding a warmer part exerts a buoyant force on it. the flow of air molecules results in a flow of heat. as the warmer part of the air moves, it is replaced by cooler air that is subsequently warmed. a continuous flow of warmer and cooler parts of air is established. the volume of a warmed part of the air is reduced and its density increases.
