At first must collect it. This can be completed by piping it via a tube, which comes out beneath a bowl of water with an upside down test tube over it. Now subsequent to collecting the gas cork it.

When the forces of attraction existing between adsorbate and adsorbent are van der Waal's forces, the adsorption is called physical adsorption. This type of adsorption is also known as physisorption or van der Waal's adsorption. Since the forces existing between adsorbent and adsorbate are very w
