Why are jet fuels more susceptible to water contamination than aviation gasoline?

Due to lower quality
Because they are stored longer
Jet fuel has a higher viscosity
Aviation gasoline evaporates quicker

The correct answer is: Jet fuel has a higher viscosity

Jet fuels are more susceptible to water contamination because they have a higher viscosity compared to aviation gasoline. The higher viscosity of jet fuel makes it more prone to absorbing water, which can lead to issues such as microbial growth, fuel system corrosion, and reduced fuel efficiency. This characteristic makes it important to adhere to strict storage and handling guidelines to prevent water contamination in jet fuel. Option A is incorrect because jet fuels are not inherently of lower quality compared to aviation gasoline. Option B is incorrect because the storage duration does not directly cause jet fuels to be more susceptible to water contamination. Option D is incorrect because the rate of evaporation of aviation gasoline does not play a significant role in its susceptibility to water contamination.
