Question

Which property is involved in the separation of noble gases by Dewar’s method?

Answer 1

1. The separation of noble gases by Dewar’s method is based on the difference in the degree of adsorption of noble gases.
2. A mixture of noble gases is passed over activated charcoal.
3. Different noble gases get adsorbed to different extents on charcoal.
4. This difference in adsorption allows their separation.

Hence, adsorption is the key property involved in Dewar’s method of separating noble gases.
