Suggest a method to liquefy atmospheric gases.

Text Solution

AI Generated Solution

To liquefy atmospheric gases, we can follow a systematic method that involves applying pressure and lowering temperature. Here’s a step-by-step solution: ### Step-by-Step Solution: 1. **Understanding Gases**: Recognize that gases consist of particles that are far apart from each other, which allows them to fill any container. This large intermolecular space is a key characteristic of gases. 2. **Applying Pressure**: To liquefy a gas, we first need to apply significant pressure. This pressure compresses the gas particles, forcing them closer together. When enough pressure is applied, the volume of the gas decreases significantly. ...

Only the surface atoms in an adsorbent play an active role in adsorption. These atoms possess some residual force such as van der Waals forces and chemical forces. In the process of adsorption. Weak adsorbate is substituting by strong adsorbete. Activated charcoal used in the gas mask is already exposed to the atmospheric air, so gases and water vapours in air are adsorbed on its surface. When the mask is exposed to chlorine atmosphere, the gases are displaced by chlorine. In general, easily liquefiable gases such as CO_(2),NH_(3),Cl_(2), and SO_(2) are adsorbed to a greater extent than the elemental gases, e.g., H_(2),N_(2),O_(2), He, etc. Gas mask works on the principle of
