What. Is. Plasma. Which. Is. Known. As. Another. 4th. Matter |
| Answer» Plasma and BEC (Bose-Einstein Condensate) are considered as states of matter other than solid, liquid and gas.\tPlasma is a mixture of free electrons and ions. Plasma occurs naturally in the stars (including the sun).\tInside the stars, the temperature is so high that the atoms break up. Some of the electrons break away from the atoms converting the rest of atoms into electrically charged particles called ions. This mixture of free electrons and ions in a star is called plasma.\tThe sun and other stars glow because of the presence of plasma in them.\tPlasma can also be made on the earth by passing electricity through gases at very low pressure taking in a glass tube. The fluorescent tubes and neon sign bulbs form plasma when they are switched on. | |
