Chapter 14  Sources of Energy Question 1: What is a good source of energy? Answer: A good source of energy fulfils the following criteria: (I)It produces a lot of heat per unit mass. (II)     It does a huge amount of work per unit mass. (III)    It is easily accessible. (IV)    It is easy to store and transport. (V)It is economical. (VI)It produces less amount of smoke. Question 2: What is a good fuel? Answer: A good fuel produces a huge amount of heat on burning, does not produce a lot of smoke, and is easily available. Question 3: If you could use any source of energy for heating your food, which one would you use and why?

Chemistry(Atoms and molecules)

                              Mole concept Important thing is first you know about  Gram Atomic Mass Gram Molecular Mass Main thing is that you should learn Atomic masses Approx from 1 to 20. The image i given for learn Atomic masses. Gram atomic masses - The amount of a substance whose mass in grams is numerically equal to its  atomic mass, is called gram atomic mass of that substance. For Example- Atomic mass of oxygen, O = 16u       so,  Gram atomic mass of oxygen , O = 16g Gram molecular mass-  The amount of a substance whose mass in grams is numerically equal to its  molecular mass, is called gram molecular mass of that substance. For Example- Molecular mass of oxygen, O = 32u       so,  Gram Molecular mass of oxygen , O = 32g So understand all above topic then you will learn mole concept. Mole-...

Chapter 15 Class 10 Science

Class–X (Our Environment) Questions 1.                   Why are some substances biodegradable and some non-biodegradable? 2.                   Give any two ways in which biodegradable substances would affect the environment. 3.                   Give any two ways in which non-biodegradable substances would affect the environment. Class–X (Our Environment) Answers 1.                   Substances which can be acted upon by microorganism (decomposer) are called biodegradable. For example- vegetable wastes, paper, cotton etc. On the other hand, materials which are not acted upon by decomposers are called non-b...
