AVGAS 100LL at a temperature of 15°C has a density of...

  • A

    0.68 kg/l.

  • B

    1.0 kg/l.

  • C

    0.82 kg/l.

  • D

    0.72 kg/l.

AVGAS 100LL (Aviation Gasoline 100 Low Lead) is a specialized type of aviation fuel used primarily in piston-engine aircraft. The density of AVGAS 100LL, like most liquids, changes with temperature.

  • As temperature increases, the density of the fuel decreases because the liquid expands.
  • Conversely, as temperature decreases, the density increases because the liquid contracts.

This temperature-dependent behavior is due to the thermal expansion property of liquids. At the standard temperature of 15°C, the density of AVGAS 100LL is approximately 0.72 kg/l. At higher temperatures, the density will be slightly less than 0.72 kg/l. At lower temperatures, the density will be slightly more than 0.72 kg/l.
