water is a kind of substance & freezing means a substance changes from a liquid into a solid by decreasing heat energy ->  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 ->  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 -> the water in the container will be changed from a liquid to a solid by decreasing heat energy
