There are two sphers of same radius and material at the same temperature but one being solid while the other hollow. Which sphere will expand more if they are given the same amount of heat ?

Explanation

To determine which sphere will expand more when given the same amount of heat, we can analyze the situation step by step.

### Step-by-Step Solution:

1. **Understanding the Problem**: We have two spheres of the same radius and made of the same material. One is solid, and the other is hollow. Both spheres are at the same initial temperature and are heated by the same amount.

2. **Volume Expansion Concept**: The volume expansion of an object when heated can be described by the formula:
