$4.$True or False: Crude oil stabilization not only reduces vapor pressure but also significantly increases the flash point of the oil, making it safer for transportation.

True or False: Fractional distillation is the only method used in refineries to separate crude oil into different components, and it can separate all types of hydrocarbons efficiently.

True or False: ASTM distillation tests are used to specify product quality for end$-$users, and they can accurately predict the performance of petroleum products in engines.

True or False: TBP distillation requires a more complex setup than ASTM distillation, and it provides more detailed information on the distillation characteristics of crude oil.
