Webb8 okt. 2024 · La convection thermique dépend du mouvement de la masse d’une région de l’espace à une autre. La convection de la chaleur se produit lorsque le flux en vrac d’un fluide (gaz ou liquide) transporte de la chaleur avec le flux de matière dans le fluide. Rayonnement thermique . WebbConvection is a process where a liquid or gas tends to rise as it is heated. This is because the material becomes less dense as it heats up causing it to rise while the colder denser material sinks due to gravity. For Example, when a hot air balloon is heated, the air inside the balloon rises.
