A change which can be reversed is called ___________ change.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Types of Changes:**
- There are two main types of changes in chemistry: physical changes and chemical changes.
- Physical changes are changes that can be reversed, while chemical changes are typically irreversible.

2. **Defining Physical Change:**
- A physical change involves a change in the state of matter (solid, liquid, gas) without altering the chemical composition of the substance.
- Examples of physical changes include melting ice, boiling water, or dissolving sugar in water.

3. **Identifying Reversible Changes:**
- Since physical changes can be reversed, they are often referred to as reversible changes.
- This means that the original state of the substance can be restored after the change.

4. **Conclusion:**
- Therefore, a change which can be reversed is called a **physical change**.

**Final Answer:**
A change which can be reversed is called **physical change**.
