Question

When heating a liquid on the stovetop, the heated liquid becomes less dense and rises and the denser cooler liquid sinks to the bottom. What type of thermal energy transfer is occurring?.

Answer 1

Natural convection

Step-by-step explanation:

Natural convection occurs when fluids are heated. When the fluid molecules are heated, the fluid becomes larger and lighter. The heated molecules take up more space and rise to the top, while the cooler molecules sink to the bottom. These cooler molecules then become heated.
