Q. Cryogenic engines find application in

  • (A) Rocket technology
  • (B) Frost-free refrigerators
  • (C) Sub-marine propulsion
  • (D) Researches in supercon-ductivity
βœ… Correct Answer: (A) Rocket technology
Explanation:

βœ… Correct Answer: (A) Rocket technology

Explanation:

A cryogenic engine uses fuels and oxidizers that are stored at extremely low temperatures, such as:

  • Liquid Hydrogen (LHβ‚‚) as fuel
  • Liquid Oxygen (LOX) as oxidizer

These engines provide high efficiency and powerful thrust, which makes them ideal for launch vehicles and rockets.

Therefore, cryogenic engines are mainly used in β†’ (A) Rocket technology. ?
