Two large holes are cut in a metal sheet will the distance between the holes increase or decrease on heating?

Explanation

To determine whether the distance between two large holes in a metal sheet will increase or decrease upon heating, we can analyze the concept of thermal expansion.

### Step-by-Step Solution:

1. **Understanding Thermal Expansion**: When a material is heated, its particles gain energy and move more vigorously. This increased movement causes the material to expand. This phenomenon is known as thermal expansion.

2. **Application to the Metal Sheet**: In our case, we have a metal sheet with two large holes. When the metal sheet is heated, the entire sheet will expand uniformly.
