Electric battery

An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons that will flow through an external

Wet cells were the first known type of electrochemical cell to generate electricity. However, their application is limited since wet cells are prompted to leak problems. Most modern applications of electrochemical batteries involve dry cells. In a dry cell, electrolytes are used as a paste rather than as a liquid, so there less likely to leak.

Changes in Matter: Physical vs. Chemical Changes

Selected text level. Matter is capable of undergoing changes, which are classified as either physical or chemical. Physical changes in matter are often reversible: An ice cube can melt into liquid water, and then the liquid water can be frozen back into an ice cube. Chemical changes, on the other hand, are not reversible: A log burned in a fire
