Which out of helium and neon would adsorb on the surface of charcoal more readily and why?

Explanation

To determine which gas, helium or neon, would adsorb more readily on the surface of charcoal, we can analyze the properties of both gases, particularly focusing on their critical temperatures and how these relate to the adsorption process.

### Step-by-step Solution:

1. **Understanding Adsorption**:
Adsorption is the process where molecules from a gas adhere to the surface of a solid. The extent of adsorption depends on various factors, including the nature of the gas and the surface area of the adsorbent.

2. **Critical Temperature**:
