In NEWS: The benefits and hazards of liquid oxygen

  • Liquid oxygen has a pale blue colour and is a cryogenic liquid. Cryogenic liquids are liquefied gases that have a normal boiling point below -238 degrees Fahrenheit (-150 degrees Celsius).

Benefits of Liquid Oxygen:

  • In commerce, liquid oxygen is classified as an industrial gas and is widely used for industrial and medical purposes. Hence statement (2) is incorrect.
  • Liquid oxygen is used as an oxidant for liquid fuels in the propellant systems of missiles and rockets. Hence statement (1) is correct.
  • Oxygen is widely applied in the metal industries in conjunction with acetylene and other fuel gases for metal cutting, welding, hardening, cleaning and melting.
  • Liquid oxygen therapyis the medical process of providing additional oxygen to a patient who cannot get enough oxygen on their own. Conditions such as asthma, lung disease and pneumonia can be treated by this method.

Hazards of Liquid Oxygen:

  • Contact with liquid oxygen can cause severe skin and eye irritation and burns as well as frostbite. Hence statement (3) is correct.
  • Similarly, Inhalation of 80 percent oxygen at one atmospheric pressure for more than 12 hours can cause irritation of the respiratory tract, nausea, dizziness, vision loss, coughing, chest pain etc.

  • An FFV is a modified version of vehicles that could run both on gasoline and doped petrol with different levels of ethanol blendsHence statement (1) is correct.
    FFVs will allow vehicles to use all the blends and also run on unblended fuel.

  • According to the NITI Aayog report, FFVs have compatible engines to run on more than 84 percent ethanol blended petrol. Hence statement (2) is correct.
  • In fact, these vehicles are a logical extension of the Ethanol Blended Petrol (EBP) programme launched by the Union Ministry of Petroleum and Natural Gas in January 2003.

About Core inflation

  • Core inflation is also a term used to denote the extent of inflation in an economy. But Core inflation does not consider the inflation in food and fuel. This is a concept derived from headline inflation.

  • Nearly 12 percent of the global population faced severe levels of food insecurity or they ran out of food and in worst situations, must have a day without food. In one year — that is 2020 — the rise in the food insecure population was more than the combined number of the last five years.
  • The overall decline in food intake has also increased hunger levels in 2020, making the primary Sustainable Development Goal of ending hunger by 2030 impossible now. Between 720 and 811 million people in the world will endure hunger in 2020. In comparison to 2019, there were an additional 161 million people who faced hunger.
