||The theoretical temperature at which no further heat loss is possible, and at which all molecular movement would cease is called absolute zero.
||Atoms are the building blocks of all matter. An atom is made up of protons, neutrons and electrons and bond together into stable groups of atoms called 'molecules'.
||An electrical charge is a quantity of electrical energy that is held by an object such as a battery. Electric charge can be directly measured with an electrometer.
||Electrical conduction is the movement of electrically charged particles due to a force exerted by an electric field. The electric current formed by this movement travels through a conductor.
||The acid solution in a vehicle battery is an electrolyte. An electrolyte is a substance that contains free ions and conducts electricity, usually a liquid.
