A change which can be reversed is called `"_____"`

Answer

To answer the question, "A change which can be reversed is called '_____'", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the term used to describe a change that can be reversed. This means that whatever change has occurred can be undone or returned to its original state.

**Hint**: Think about everyday changes that can go back to their original form.

2. **Identifying Examples**: One common example of a reversible change is the melting of ice. When ice (solid H2O) melts, it turns into water (liquid H2O). This process can be reversed by freezing the water back into ice.

**Hint**: Consider changes that involve states of matter, like solid, liquid, and gas.

3. **Defining the Term**: The term that describes a change that can be reversed is "reversible change." This means that the original substance can be obtained again after the change.

**Hint**: Look for a word that starts with "re-" indicating something can go back to its original state.

4. **Connecting to Physical Changes**: Reversible changes are often classified as physical changes. This is because they do not alter the chemical composition of the substance, just its physical state.

**Hint**: Think about how physical changes differ from chemical changes, which cannot be easily reversed.

### Final Answer:
A change which can be reversed is called **"reversible change."**
