Question
When a liquid is heated in a container, which of the
following processes primarily causes the heat transfer within the liquid? ÂSolution
In liquids and gases, convection is the primary mode of heat transfer.  Hot liquid becomes lighter (lower density) and rises, while cooler liquid (higher density) sinks, creating convection currents.  Conduction happens mainly in solids; radiation involves electromagnetic waves and does not need a medium.
