Which two forms of heat transfer work together to heat water in a plastic bottle

The two forms of heat transfer that work together to heat water in a plastic bottle are conduction and convection.

Heat is transferred through solid materials by a process known as conduction.

In liquids, heat is transferred by convectional currents.

For water in a plastic bottle, heat will first have to travel through the solid plastic bottle by conduction before heating the water inside the bottle by convection.
