A trail is created by jet-planes as they release____ through the exhaust.
Carbon-di-oxide
Water vapours
Carbon monoxide
Hydrogen
- Jet planes create trails, commonly known as contrails.
- These trails form when the water vapor in the exhaust from jet airplanes condenses into ice crystals.
- Option 2: Water vapours
- Water vapor in the exhaust freezes to form trails.
- Cold, humid air at high altitudes helps in this formation.
- Carbon dioxide, carbon monoxide, and hydrogen are also found in exhaust emissions, but they do not directly create trails in the sky.
- Option 1: Carbon dioxide
- This is a greenhouse gas, not linked to trail formation.
- Option 3: Carbon monoxide
- A pollutant rather than a trail-forming substance.
- Option 4: Hydrogen
- Present in emissions but does not impact trail visibility.
