Mention the factors on which the existence of matter in a particular state depends.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the factors that determine the existence of matter in a particular state (solid, liquid, gas).

2. **Identifying the Factors**: There are two main factors that influence the state of matter:
- **Temperature**: The temperature of a substance affects its state. For example, when a solid is heated, its temperature increases, and it may reach a point called the melting point where it changes from solid to liquid.
- **Pressure**: The pressure applied to a substance can also change its state. For instance, if we apply pressure to a gas, it can compress and change into a liquid.
