- Water is a kind of substance
- Freezing means a substance changes from a liquid into a solid by decreasing heat energy
- Therefore, decreasing the heat energy of water will change water from a liquid into a solid

- Heat is taken away from a container of water
- Taking heat away from water means decreasing heat energy of the water
- So, the heat energy of the water in the container is decreasing

- Decreasing the heat energy of water will change water from a liquid into a solid
- The heat energy of the water in the container is decreasing
- Hence, the water in the container will be changed from a liquid to a solid by decreasing heat energy

So, the water in the container will be changed from a liquid to a solid by decreasing heat energy
Question: If enough heat is taken away from a container of water, what will happen to the water?
Context: - Heat is taken away from a container of water 
- Water is a kind of substance 
- Freezing means a substance changes from a liquid into a solid by decreasing heat energy
