A mixture of two or more gases can be separated by

Options

A. Sedimentation
B. Liquefication
C. Distillation
D. Decantation

Answer

To separate a mixture of two or more gases, we can use the process of distillation. Here's a step-by-step solution:

### Step-by-Step Solution:

1. **Understanding the Mixture**: Recognize that we have a mixture of two or more gases that need to be separated.

2. **Liquefying the Gases**: Since distillation is a method used for separating liquids based on their boiling points, we first need to convert the gases into liquids. This can be achieved by applying high pressure to the gas mixture, which causes the gases to liquefy.

3. **Distillation Process**: Once the gases are liquefied, we can use distillation to separate them. Distillation works on the principle that different substances have different boiling points.

4. **Heating the Liquid Mixture**: The liquefied gas mixture is then heated. As the temperature increases, the component with the lower boiling point will vaporize first.

5. **Collecting the Distillate**: The vapor produced from the component with the lower boiling point is collected and can be condensed back into a liquid. This process continues until all components have been separated based on their boiling points.

6. **Final Separation**: The gas with the higher boiling point will remain in the distillation apparatus until the temperature is high enough for it to vaporize, at which point it can also be collected.

### Summary:
In summary, to separate a mixture of two or more gases, we first liquefy the gases by applying high pressure, then use distillation to separate them based on their boiling points.
