Solution

The correct option is A Compress and cool nitrogen
Molecules comes closer and as a result merges and forms liquid. And since nitrogen is less heavier it will be in upper side of coloumn.

Q. In fractional distillation of air, is obtained in solid form when the air is compressed and cooled.

Q. In fractional distillation, the cooled and compressed air is passed through:

Fractional distillation is the separation of a mixture into its component or fractions. This process is based on difference in boiling point of the components in the mixture. This is a special type of distillation.

Air is a homogeneous mixture of 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases such as helium, krypton, nitrogen dioxide etc.

Consider three gases oxygen, nitrogen and argon whose boiling points are: -183, -196, -186 degree celsius. They are to be separated from air using fractional distillation.

Air is compressed by increasing pressure and is then cooled by decreasing the temperature to form liquid air. This 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. As the height of tower increases the temperature increases.

Among the three gases, which gas is collected at last?

Fractional Distillation is the separation of a mixture into its component parts or fractions. This is the process of separation of chemical compounds by their boiling point, the mixture is heated to a temperature at which one or more fractions (component parts) will vaporize. Generally the component parts boil at less than 25°C from each other under a pressure of one atmosphere. It is a special type of distillation.

State True of False:

Statement: The temperature is low at the base of the Fractional Distillation.

Consider three gases oxygen, nitrogen and argon whose boiling points are -183, -196, -186 degree celsius, they are to be separated from air using fractional distillation.

Air is compressed by increasing the pressure and then cooled by decreasing the temperature in order to get liquid air. This 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. As the height of tower increases the temperature increases.

Statement: The temperature is ____ at the base of the fractional distillation column.
