Static GK decides the General Awareness score in SSC CHSL. Of the 25 questions in Tier-I and the 20 in Tier-II, most come from Indian Polity, History, Geography, the Economy and General Science, the areas the CHSL 2026 notice lists as History, Culture, Geography, Economic Scene, General Policy and Scientific Research relating to India and its neighbouring countries. The level is that of Class 12, so the questions are direct: which article, which river, which ruler, which year. Polity asks about parts and schedules of the Constitution, fundamental rights, the President, Parliament, the Supreme Court and constitutional bodies. History covers the Indus Valley, the Mauryas and Guptas, the Sultanate and Mughal periods, and the freedom struggle from 1857 to 1947. Geography asks about rivers, soils, climate, national parks, minerals and world physical features. The Economy part asks about budget terms, the RBI, banking and basic concepts. General Science is school-level Physics, Chemistry and Biology with everyday applications, and Culture covers dances, festivals, monuments and books. This page holds GK24's topic-wise GK notes for SSC CHSL, written as short facts and tables so a topic can be revised in one sitting. Read a topic, then solve its previous-year questions and quiz on this site to check what you retained.
On which day of the National Postal Week was the Digital Detox Campaign held?
Philately means the collection and study of postage stamps, so a campaign built around stamped postcards fitted the theme of the day.
Read the full explanation →The Digital Detox Campaign of the Department of Posts was organised in collaboration with which airline?
The Department of Posts under the Ministry of Communications worked with this airline for the campaign, under which travellers on selected flights were given specially designed digital detox kits containing postcards.
Read the full explanation →Which body set up the National Culture Fund that is a party to this agreement?
The National Culture Fund was established by that ministry to make partnerships possible between the government and the corporate sector for conserving and promoting India's tangible and intangible cultural heritage, and this agreement is an example of that purpose at work.
Read the full explanation →At which of the three sites in the agreement is the work planned in the North Bazaar and South Bazaar areas?
The projects there take in the historic North Bazaar and South Bazaar areas, where development work is proposed over a stretch of about 270 metres in the first and about 250 metres in the second.
Read the full explanation →How much financial support has HAL approved in principle for the heritage conservation projects?
Hindustan Aeronautics Limited accorded in-principle approval for financial support of this amount, to be used over the financial years 2026-27 to 2028-29, and the spending forms part of the company's corporate social responsibility effort.
Read the full explanation →Which three heritage sites are covered by the memorandum of agreement signed by HAL, NCF and ASI?
The agreement signed by Hindustan Aeronautics Limited, the National Culture Fund and the Archaeological Survey of India covers conservation and development work at Hampi in Karnataka, the Taj Mahal at Agra in Uttar Pradesh and Bekal Fort in Kerala.
Read the full explanation →Which one of the following statements about gravitational force is NOT correct?
This statement is wrong: the gravitational force between two bodies depends on their masses and on the distance between them.
Read the full explanation →A sample of oxygen contains two isotopes of oxygen with masses 16 u and 18 u respectively. The proportion of these isotopes in the sample is 3 : 1. What will be the average atomic mass of oxygen in this sample?
Three parts of oxygen-16 and one part of oxygen-18 give an average of (3 × 16 + 1 × 18) ÷ 4 = 66 ÷ 4 = 16.5 u. Isotopes are atoms of the same element with the same atomic number but different mass numbers, because they have different numbers…
Read the full explanation →Which one of the following statements is correct ?
In boiling, bubbles of vapour form throughout the liquid; in evaporation, only molecules at the surface escape.
Read the full explanation →Which one of the following is not used as raw material in the manufacture of glass ?
Gypsum (calcium sulphate dihydrate) is not a raw material for glass; it is added to cement to slow down its setting.
Read the full explanation →Which one of the following is a chemical change?
Bacteria turn the lactose in milk into lactic acid, a new substance, so souring is a chemical change that cannot be reversed.
Read the full explanation →The commercial unit of electrical energy is kilowatt-hour (kWh), which is equal to
One kilowatt-hour is the energy used by a 1 kW appliance running for one hour: 1000 W × 3600 s = 3.6 × 10⁶ J. The joule is too small for household bills, so electricity companies charge in kilowatt-hours, commonly called units.
Read the full explanation →Consider the following reaction :
Fe₂O₃(s) + 2Al(s) → 2Fe(s) + Al₂O₃(s)
Which of the following statements about the given reaction is NOT correct ?
This is the thermite reaction, which is highly exothermic: it gives out so much heat that the iron formed comes out molten.
Read the full explanation →Which one of the following wavelength radiations may correspond to an X-ray ?
X-rays have wavelengths from about 0.01 nm to 10 nm, so 1 nm lies well inside the X-ray band. In the electromagnetic spectrum, wavelength decreases from radio waves through microwaves, infrared, visible light and ultraviolet to X-rays and gamma rays.
Read the full explanation →The atomic number of an element is 8. How many electrons will it gain to form a compound with sodium?
The element with atomic number 8 is oxygen, which gains two electrons to complete its octet and forms sodium oxide, Na₂O. Oxygen's electrons are arranged as 2, 6, so it needs two more to reach the stable arrangement 2, 8 of neon.
Read the full explanation →Which one of the following energy is stored in the links between the atoms ?
Chemical energy is the energy stored in the bonds that link atoms together in molecules. When a chemical reaction breaks old bonds and forms new ones, this stored energy is released or absorbed.
Read the full explanation →Which one of the following statements about glass is not correct ?
This statement is wrong: soda glass is the soft glass, while pyrex is a hard borosilicate glass. Ordinary soda-lime glass is made from silica (sand), sodium carbonate and limestone; it softens at a fairly low temperature and is used for windows, bottles and tumblers.
Read the full explanation →Refining of petroleum is carried out using which one of the following techniques?
Crude petroleum is a mixture of hydrocarbons with different boiling points, and fractional distillation separates them. In a refinery, crude oil is heated to about 400 °C and its vapour enters a tall fractionating column that is hot at the bottom and cooler towards the top.
Read the full explanation →Which one among the following separation techniques is used for blood tests in diagnostic laboratories ?
Diagnostic laboratories spin blood samples in a centrifuge to separate the plasma or serum from the blood cells. In centrifugation a sample is rotated at high speed, so the denser particles are pushed to the bottom of the tube and the lighter liquid stays on top.
Read the full explanation →Which one among the following statements is correct?
One pascal is defined as a force of one newton acting on an area of one square metre. Pressure is force per unit area, and its SI unit, named after the French scientist Blaise Pascal, is the pascal (Pa): 1 Pa = 1 N/m².
