OTHERS STATES OF MATTER

Plasma

The state consists of super energetic and super excited particles. These particles are in the form

ionised gases. The fluorescent tube and neon sign bulbs consist of plasma.

Bose-Einstein Condensate

→ Indian physicist Satyendra Nath Bose made a study regarding the fifth state of matter. Base

his study, Albert Einstein predicted a fifth state of matter called the Bose-Einstein Condensate.

→ The Bose-Einstein Condensate or BEC is formed by cooling a gas of extremely low density to

low temperatures.

 Conversion of Temperature –

→ Kelvin is the SI unit of temperature, C = 273.16

For convenience, we take 0° C = 273 K

after rounding off the decimal. To change a temperature

on the Kelvin scale to the Celsius scale you have to subtract 273 from the given temperature, and to convert a temperature on the

Celsius scale to the Kelvin scale you have to add 273 to the given temperature.

→ Atmosphere (atm) is a unit of measuring pressure exerted by a gas. The unit of pressure is Pascal.

(Pa): 1 atmosphere = 101325 Pa.

 The pressure of air in atmosphere is called atmospheric pressure & atmospheric pressure at sea level is 1 atmosphere, and is taken as the normal atmospheric

pressure.
