Solution

In solids, heat transfer occurs predominantly through conduction. This is because solids have molecules packed tightly which makes it easy for them to pass heat. Whereas in liquids convection takes place because the molecules are spread further apart. Radiation is the mode of heat transfer which does not require any medium.
