GAS
The state of matter which has fluidity, highly
compressible and does not have definite shape & volume is
called as a Gas.
Example: Air, Clouds, Smoke etc

PROPERTIES OF GASES
1. Non Definite volume
2. Not definite shape
3. Fluidity
4. Minimum Density
5. More Diffusion
6. High Compressibility
7. Exert Pressure

PROPERTIES OF GAS
1. Not definite shape
2. Not definite volume(Occupy whole container)
(Intermolecular Space is more &
Force of Attraction is less)

6. 6
DKPatilInstituteofPharmacy
PROPERTIES OF GAS
3. Non Rigid i.e. Maximum Fluidity
(Fluidity is the ability to flow)
(Its due to Intermolecular Space is more &
Force of Attraction is less)
Example: Gas in baloon before & after pressing

PROPERTIES OF GAS
4. Minimum Density
DENSITY = Mass / Volume(gm/ml)
Example: 1kg each of Ice, Water, Vapor have different densities
DENSITY

8. 8

PROPERTIES OF GAS
5. It undergo DIFFUSION
(Spontaneous Intermixing Of Particles Of One Matter To
Another)
Example: Balloon gets deflate after some time due to diffusion
of gas

PROPERTIES OF GAS
6. Highly Compressible
Solids < Liquids < Gases
Example: Liquefied gas, LPG, Sprays

PROPERTIES OF GAS
6. Exert Pressure
Pressure = Force/ Area
• Kinetic energy of gases is high, leading to free movement
of particle in random direction
• This causes collision with other particles & walls of
container
• So they EXERT PRESSURE.
Example: Gas in container

PLASMA
The Plasma is fourth state of matter which posses
ionized gases & free electrons.
1. When electricity passes through the gases it get
ionized and starts glowing, state is called Plasma.
2. Plasma state exists normally at 10000-150000C.
3. Sun. Stars glow due to Plasma state of matter
caused by high temperature.
4. In Universe 99% of matter is Plasma.
5. Plasma is highly energetic matter.
Example: Florescent tubes, Neon sign bulbs, Compressed
fluorescent light(CFL) etc

BOSE EINSTEIN CONDENSATE
(BEC)
1. Satyendra Bose(Indian Physicist) & Albert Einstein gave
fifth state of matter i.e. BEC in 1920.
2. In 2001, Eric. A. Cornell, Wofgan Ketterlle, Karl. E.
Wieman(USA) got Nobel Prize for BEC.
3. BEC is formed when very Low density gas(1000 times less
than air) is cooled at low temperature of absolute 0
temperature)
4. Absolute 0 Temperature = 00K = -2730C
5. At this temperature movement of molecules stops and they
start clumping resulting in SUPER ATOM.
Example: Super fluid(Liquid He at Absolute temp.) etc
