Is burning paper a chemical change?
Physical changes involve changes in the form of a substance, but not its chemical composition. As we burn paper, it changes into ash i.e., changes its chemical composition. Hence, it is a chemical change not a physical one. Q.
Is cooking a chemical change?
When you bake a cake, the ingredients go through a chemical change. A chemical change occurs when the molecules that compose two or more substances are rearranged to form a new substance! When you start baking, you have a mixture of ingredients. The flour, egg, sugar, etc.
Why is chemistry called the science of life?
The study of the structure and function of these biomolecules, as well as their role in biological processes at the molecular, cellular, and organismal levels, is known as the Chemistry of Life.” Cells are made up of organic and inorganic molecules, which are made up of atoms that have been bonded together.
