NCERT Solutions for Class 11 Chemistry

Matter can be defined as anything which has mass and occupies space. There are three states of matter namely Solid, Liquid and Gas.

Solid: Solid consists of particles which are tightly bound together. They have fixed geometrical shape.
Liquid: They are loosely bound particles and do not have any fixed shape but they take the shape of the container in which they are kept.
Gas: Gases consists of very loosely bound particles and do not have any shape.

Some of the basic physical unit of matter or fundamental SI units are as follows:

Mass – Kilogram (kg)
Length – Meter (m)
Time – Seconds (s)
Luminous intensity – Candela (Cd)
Amount of substance – Mole (mol)
Temperature – Kelvin (K)
Electric current – Ampere (A)

Mixtures are of two types: Homogeneous and Heterogeneous.

Homogeneous Mixtures: Homogeneous mixture can be defined as a mixture where the composition of the mixture is uniform throughout.
Heterogeneous Mixtures: Heterogeneous types of mixture are those where all the elements don't mix.
