Solution:
The above statement is false.In general, the burning of crackers is a chemical change. The reason behind this is it produces new products with different properties. Also, this chemical change produces heat, light and smoke. The food is broken down into smaller molecules throughout the process of digestion. In addition, the salivary glands in our mouth help break down food. During this process, there is a formation of a new substance.
The corrected statement would be, “Burning crackers and food digestion are chemical changes”.
