Chemistry is that branch of science which deals with the composition, structure and properties of matter. Organic chemistry is predominantly concerned with the reactions that organic molecules undergo. Hydrocarbons are compounds that contain only carbon and hydrogen atoms. Carboxylic acids contain both a carbonyl group (C=O) and a hydroxyl group (–OH) on a terminal carbon. Carboxylic acids, like aldehydes, are terminal functional groups.

Class 10 - Science - Chapter 14 

Sources Of Energy 

Study Points

Energy:  

Whenever a body is capable of doing work, the body is said to possess energy. Thus energy is defined as the ability of a body to do work and the amount of energy possessed by a body is equal to the amount of work it can do when its energy is released.

Energy comes in different forms and one form can be converted to another. For example, if we drop a plate from a height, the potential energy of the plate is converted mostly to sound energy when it hits the ground.

A good source of energy should be:

i) Safe and convenient to use, e.g., nuclear energy can be used only by highly trained engineers with the help of nuclear power plants. It cannot be used for our household purposed.

ii) Easy to transport, e.g., coal, petrol, diesel, LPG etc. Have to be transported from the places of their production to the consumers.

iii) Easy to store, e.g., huge storage tanks are required to store petrol, diesel, LPG etc.
