!. Scientists have discovered two more states of matter in
addition to solid, liquid and gases. Discuss these two states
in detail.
Answers
Plasma is not a common state of matter here on Earth, but may be the most common state of matter in the universe. Plasma consists of highly charged particles with extremely high kinetic energy. The noble gases (helium, neon, argon, krypton, xenon and radon) are often used to make glowing signs by using electricity to ionize them to the plasma state. Stars are essentially superheated balls of plasma. [Related: Properties of Matter: Plasma]Sublimation
When a solid is converted directly into a gas without going through a liquid phase, the process is known as sublimation. Sublimation occurs when kinetic energy of the particles is greater than atmospheric pressure surrounding the sample. This may occur when the temperature of the sample is rapidly increased beyond the boiling point (flash vaporization). More commonly, a substance can be "freeze dried" by cooling it under vacuum conditions so that the water in the substance undergoes sublimation and is removed from the sample. A few volatile substances will undergo sublimation at normal temperature and pressure. The best known of these substances is CO2 or “dry ice.”
Answer:
First state: Solid
Second state: Liquid
Third state: Gas
Fourth state: Plasma
Fifth state: Bos Einstein Condensate (BEC)
BEC:
in 1924 Albert Einstein and satyendra nath Bose predicted Bose Einstein condensate (BEC) which is referred as the fifth state of matter.
PLASMA:
A plasma is a hot ionized gas consisting of approximately equal numbers of positively charged ions and negatively charged electrons.
