Question

explain states of matter briefly

Answer 1

In physics, a state of matter is one of the distinct forms that matter takes on. Fourstates of matter are observable in everyday life: solid, liquid, gas, and plasma.

Answer 2

There are 5 states of matter:

1. SOLID:  - In this state, the particle of matter are located very close to each other and have high force of attraction b/w them.
                 - Incompressible
                 - Highly rigid
                 -Fixed shape
                 -Fixed volume
                 -Can't flow

2. LIQUID:  -More intermolecular space
                   -Less intermolecular force of attraction
                   -No fixed shape. Take the shape of the container
                   -Have a fixed volume.
                   -Less rigid
                   -Slightly compressible
                   -Can flow

3. GASEOUS: -No fixed shape, no fixed volume
                        -High intermolecular spacing
                        -Least rigid
                        -Highly compressible
                        -Can flow
                        -Least intermolecular forces of attraction

4. PLASMA: When a gas is heated to a extremely high temperature (appox. 5773 K) in low pressure, ionisation takes place. The system as a whole is neutral, but it contains free cations and electrons. This is called plasma

5. BOSE-EINSTEIN CONDENSATE (BEC):  It is formed when a gas of extremely low density is cooled to super low temperature of 0K (-273 degree celsius) or Absolute Zero (at present, impossible to achieve)
