A block of chocolate is melting on a hot pan is a example of conduction from the oven conducting the heat that touch’s the pan.

What is conduction ?

The term conduction is defined as the process in which heat is transferred from the hotter end to the colder end of an object. Temperature is a measure of the amount of kinetic energy processed by the particles in a sample of matter.

Conduction is the conversion of heat energy from one substance to other or within a substance. After some time, the handle of the spoon will become hot. This is due to transfer of heat energy from molecule to molecule or from atom to atom.

Thus, A block of chocolate is melting on a hot pan is a example of conduction from the oven conducting the heat that touch’s the pan.

Both acids and bases conducts electricity and water.

When acid dissolves in water, they are good electrolytes.

When bases dissolves in water they are good electrolytes.

Electrolytes are liquid or molten substances that are able to conduct electricity.

they conduct electricity by the use of their ions in solution.

Since acid and bases ionize in solution, they will conduct electricity.

An acid is a substance that produces excess hydroxonium ion in solution.

A base produces excess hydroxyl ions in solution. Hope This Helps!
