What type of heat transfer is a beaker on a hot plate an example of?

Heat transfer to a beaker on a hot plate is an example of conduction.

Explanation:

Conduction is a process where heat is transferred from one particle to another particle. Conduction is mainly possible in case of solids.In case of solids the atoms as well as the molecules are tightly packed through which the kinetic energy can easily pass. Conduction takes place when both the objects are touching each other. But in case of liquids molecules are loosely packed as a result convection takes place.

a electronegativity decreases beacuse the size of nucleus is bigger.
