It is then cooled and

solidifies into a solid state.

It is important to clarify what "it" refers to in the given statement. Assuming "it" refers to a liquid or solution, here are the steps for cooling it:

1. Prepare a container or vessel to hold the liquid or solution.
2. Use a thermometer to measure the current temperature of the liquid.
3. Determine the desired final temperature for the liquid.
4. Select a method for cooling the liquid based on the volume and properties of the liquid. Some common methods include:

- Placing the container in a refrigerator or cooler
- Using ice or cold water bath
- Utilizing a cooling system or refrigeration equipment

5. If using a refrigerator or cooler, place the container inside and ensure a stable and even cooling environment.
6. If using an ice or cold water bath, fill a larger container with ice or very cold water, then place the container with the liquid inside the bath, making sure the liquid is fully submerged.
7. If using a cooling system or refrigeration equipment, follow the manufacturer's instructions for proper setup and operation.
8. Monitor the temperature of the liquid using the thermometer at regular intervals.
9. Continue the cooling process until the desired final temperature is reached.
10. Once the liquid has cooled to the desired temperature, remove it from the cooling environment and proceed with any further steps as needed.
