if engery never dies, why do batteries die?

Answer 1

energy never dies, but it can be redistributed.. batteries change energy into mechanical energy that can be absorbed through friction and transformed into heat..

Answer 2

A battery is a device that converts chemical energy into electrical energy.

Batteries die because; They can no longer accept or release energy.



DEFINE
chemical energy - that part of the energy in a substance that can be released by a chemical reaction
energy - (physics) the capacity of a physical system to do work; the units of energy are joules or ergs; "energy can take a wide variety of forms"

DEFINE
electrical energy - energy made available by the flow of electric charge through a conductor

Batteries, or dry cells, operate by connecting, through a circuit, a material that wants to donate electrons to another material that lacks electrons. These are called a reducer or reducing agent and an oxidizer or oxidizing agent, respectively. The process is one of many oxidation-reduction reactions that include the rusting of iron and the bleaching of clothing.

When an oxidizer and a reducer meet, as in batteries, chemical reactions occur in both and electrons are transferred. The electron transfer creates a direct current (DC). In typical batteries, this is 1.5 volts.

One of the first oxidizers to be studied in detail was elemental oxygen. Oxygen gains electrons from other substances such as iron, causing the material to be oxidized. When iron becomes oxidized, it bonds to oxygen molecules to create iron oxide, or rust. Many other oxidizers exist, including bromine, chlorine, and fluorine. In conventional batteries, manganese dioxide powder is used as an oxidizer, turning into manganese oxide when it is depleted.

The term reducer is from metallurgy, and refers to a chemical reaction in which a substance loses electrons. The chemical transformation is one from an oxide, like iron oxide, to a non-oxide such as iron. This chemical process has long been used to turn ores into pure metals, and is so named because the reaction causes the sample to lose some mass. In conventional batteries, the reducer is zinc.

Batteries looks like a single thing, but they're actually two things – an oxidizer and a reducer placed close to each other and separated by a barrier. Each is connected to an electrode on opposite sides of the battery, which are called positive and negative depending on which substance they correspond to. When the circuit between the positive and negative electrode is completed, the electrons flow and continue to flow until equilibrium has been reached.

Usually, batteries are connected to an external load, which draws power from the electron current. Sometimes, the DC current is connected to an alternator, which converts it into alternating current (AC), which is the kind of electricity used by our household appliances. Batteries have not been fundamentally changed since they were first invented, and they are a noticeable weak spot for the field of electronics, in which price-performance increases are historically exponential.

Answer 3

Energy: is a concept which involve things like intertia.. and all atoms constituents having wavelengths.

Batteries don't really die. The potential difference between the anode and the cathode has just gone to zero thats all.. this means that the electrons (which are responsible for the tiny electricity) has all moved to the other metal..

The concept of a battery comes from the fact that some metals are more reactive then others. (they like to suck out the electrons from other metals more strongly) so on and so forth. so.. batteries don't really die.. their just satisfyed and can't be bothered moving. =)

Answer 4

First of all, the only reason energy does not 'die' is because it does not 'live'. I believe you are referring to the fact that energy cannot be destroyed.

To answer your question, the energy in a battery is used by the appliance (or whatever) and converted into electricity, which can then be used (by being converted into light, for example).

Hope this helps,

Answer 5

Energy never disappears, but it does change form. When batteries die, the energy that was in them has not disappeared (died), but has been transformed entirely. For instance, if you put batteries in a flashlight, when the batteries die, all the energy inside them has been transformed into light.

Answer 6

energies never dies due to the conservation of energy, the total energy in an isolated system remains a constant.

therefore, the battery doesnt die, it cant be used as it has converted all of its stored energy to electrical energy

Answer 7

Because the potential energy of the battery is converted into Kinetic or Sound, or Light energy when the object preforms its function. The energy from there becomes different forms...

Answer 8

The chemical energy in the battery gets converted to electrical energy that in turn gets used up running whatever. When the chemical reaction runs out, so does the electricity.

It doesn't die, it gets used.

Answer 9

Energy cannot be destroyed. It can be moved. When the battery is dead then all the energy has been moved out of the battery. Just because you pour all the water out of your glass doesn't mean the water has been destroyed does it?

Answer 10

Batteries die technically mean it's magnetic energy is covert into thermal energy to power something. So energy is just transfer from one form into another. It doesn't die.

Answer 11

The energy from the battery goes into whatever the battery is powering...it doesn't die it goes somewhere else
