$13.$True or False: ASTM distillation tests are conducted at standard atmospheric pressure to assess the boiling range of crude oil, providing critical data for refining operations.

True or False: Desalting is a temperature$-$dependent process, with higher temperatures leading to more effective removal of salts and water from crude oil.

True or False: The degree of separation $(5-95$ gap$)$ in distillation is a key indicator of crude oil quality, with a larger gap suggesting a more valuable and easier$-$to$-$refine crude.

True or False: The degree of difficulty of separation $($t$50)$ is a critical parameter for designing refinery distillation units, as it directly impacts energy consumption and operational efficiency.
