Question

at what will be the boiling point of oxygen for fractional distillation so it can be separated option a - 183 degree Celsius option b 183 degree Celsius option c - 90 ke option d 456 ke​

Answer 1

Answer:

The liquid air is allowed to warm-up slowly in a fractional distillation column, where gases get separated at different heights depending upon their boiling points. Liquid nitrogen having the boiling point of 196oC boils to form liquid nitrogen gas and is collected from the upper part of the column.
