NCERT Solutions for Class 10 Science: Chapter-wise Notes

NCERT Solutions for Class 10 Science Chapter-wise Notes have been provided below:

Chemical Reactions

The transformation of chemical substance into a new chemical substance by making and breaking of bonds between different atoms is known as Chemical Reaction

Also check:

Acids, Bases and Salts

An acid is defined as a substance whose water solution tastes sour, turns blue litmus red and neutralizes bases. A substance is called base if its aqueous solution tastes bitter, turns red litmus blue or neutralizes acids. Salt is a neutral substance whose aqueous solution does not affect litmus. 

Also check:

Metals and Non-metals

Metals are elements that are hard due to the presence of a strong metallic connection between the atoms. Non-metals are soft components.

Also check:

Carbon and its Compounds

Carbon compounds are compounds whose molecules contain a carbon atom. They are chemical substances where a carbon atom has bonded to an atom of another element. 

Also check:

Periodic Classification of Elements

Periodic classification of elements is the method by which elements are grouped on the basis of their characteristics i.e. we keep the elements that are alike in one group and the rest of the elements in the other group.

Life Processes

Life processes are the common essential processes or things that a living thing has to perform for them to live or survive.

Also check:

Control and Coordination

Control is defined as the power of restraining and regulating by which a process can be started, regulated in pace to speed up or slow down or stop completely. Coordination can be defined as the working together of the different systems of an organism in order to produce an appropriate reaction to stimuli.
