  • He led the Shatarshal army in the battle of Bhatwara in 1761 AD.
  • He is known as Durgadas Rathore of Kota. 
  • The title of Rajrana has been given to him by the Udaipur Maharana.
  • He made a treaty with the British for the post of Diwan in 1818 AD.

Additional Information

•  Rav Ram Singh-
  • He was the son of Kishore Singh II.
  • He participated in the Jajau war on behalf of Azam and died there.
  • He roasted the enemies with his cannons, hence he is called Bhabhbhujanya.
• Madho Singh-

• Mukund Singh-
  • He was the son of Madho Singh.
  • He was killed while fighting against Aurangzeb in the Battle of Dharmat.
  • He built the Amli-Meeni Mahal.

The correct answer is Sulphur Cycle

Key Points

• The sulphur reservoir is in the soil and sediments where it is locked in organic (coal, oil and peat) and inorganic deposits (pyrite rock and sulphur rock) in the form of sulphates, sulphides and organic sulphur.
• It is released by weathering of rocks, erosional runoff and decomposition of organic matter and is carried to terrestrial and aquatic ecosystems in a salt solution.
• The sulphur cycle is mostly sedimentary except two of its compounds, hydrogen sulphide (H2S) and sulphur dioxide (SO2), which add a gaseous component.
• Sulphur enters the atmosphere from several sources like volcanic eruptions, combustion of fossil fuels (coal, diesel etc.), from the surface of the ocean and gases released by decomposition.
• Atmospheric sulphur dioxide is carried back to the earth after being dissolved in rainwater as weak sulphuric acid (acid rain).
• Sulphur bound in a living organism is carried back to the soil, to the bottom of ponds and lakes and seas through excretion and decomposition of dead organic material.

Hence, “ETHIC” is written as “57239”

The correct answer is Mercury.

Key Points

• Mercury is used in thermometers because it remains in liquid form throughout a wide range of temperatures i.e -37.89 degrees Fahrenheit to 674.06 degrees Fahrenheit.
• The mercury thermometer was invented by physicist Daniel Gabriel Fahrenheit in Amsterdam.
• Mercury has a greater coefficient of thermal expansion than alcohol. 
• A thermometer with alcohol is used to measure low temperature because its freezing point is low i.e -1170C.
• It is Impossible to measure high temperatures because it’s a low boiling point.
• The thermometer with mercury cannot be used to measure the very low temperature because its freezing point is high i.e -400C.
• Mercury is the only one in liquid state at room temperature.
• It's used in thermometers because it has a high coefficient of expansion.
• It also has a high boiling point which makes it very suitable to measure higher temperatures. 
• It has a shiny appearance and doesn't stick to the glass surface of the glass.
