Given :

Mass of granite , m = 20 g .

Change in temperature , \Delta T=29-10=19^oC.

Specific heat capacity of granite , C=0.79\ J/g^oC .

To Find :

The heat absorbed by granite .

Solution :

We know , heat absorb is given by :

\Delta H=mC\Delta T\\\\\Delta H=20\times 0.79 \times 19 \ J\\\\\Delta H=300.2\ J

Therefore , heat absorb is 300.2 J .

Hence , this is the required solution .

Elements in the same column of the periodic table have what in common?
Kipish [7]

Answer:

Elements in same column of periodic table have same properties.

Explanation:

The elements in the same group have same number of valance electrons thus have similar properties.

Consider the elements of group two i.e alkaline earth metals. All have two valance electrons and show similar properties.

Magnesium, barium, calcium etc.

All alkaline earth metals form salt with halogens.e.g,

Mg   +   Cl₂    →    MgCl₂

Ba    +   Br₂    →     BaBr₂

Mg   +   Br₂    →     MgBr₂

Ca    +   Br₂    →     CaBr₂

They react with oxygen and form oxides of respective metal.

2Mg   +   O₂   →    2MgO

2Ba   +   O₂   →    2BaO

2Ca   +   O₂   →    2CaO

these oxides form hydroxide when react with water,

MgO  + H₂O   →  Mg(OH)₂

BaO  + H₂O   →  Ba(OH)₂

CaO  + H₂O   →  Ca(OH)₂

With nitrogen it produced nitride,

3Mg + N₂     →  Mg₃N₂

3Ba + N₂     →  Ba₃N₂

3Ca + N₂     →  Ca₃N₂

With acid like HCl,

Mg + 2HCl  →  MgCl₂ + H₂

Ba + 2HCl  →  BaCl₂ + H₂

Ca + 2HCl  →  CaCl₂ + H₂

arrow_backSources of Information on Modern Indian History

Summary

Videos

References

A primary source of information for historians is the official records of the British administration. The British kept written records of every key instruction, meeting, transaction, investigation, plan, policy decision and agreement. They attached record rooms with all the important administrative institutions.

The British built specialized institutions like museums and archives to preserve important documents.

Historians gather important information about the provincial administrative system from the reports, memos, notings and letters preserved in the 19th century in the archives and record rooms across India.

For effective administration, the British carried out a number of surveys in the early 19th century.

By the end of the 19th century, censuses of all the Indian provinces were being carried out every ten years. This helped to collect information on the religion, caste and occupation of the people. These surveys have helped historians to collect information about modern India.

Personal diaries of personalities like Jawaharlal Nehru and Sardar Vallabhbhai Patel, newspapers, popular books like The Discovery of India and Glimpses of World History, autobiographies of personalities like Mahatma Gandhi, and accounts of travellers and pilgrims give a deep insight into the lives of the common people.
