The explosion of fireworks is a chemical change, as it involves a rapid release of energy and the creation of new substances.
Burning of wood is also a chemical change, as it involves the combustion process where wood reacts with oxygen to produce heat, light, and new substances like ash and smoke.
Baking cake batter into a cake is a chemical change, as it involves the reaction between the ingredients (such as flour, eggs, and baking powder) under heat, leading to the formation of a new product with different properties.
Shaping a gold bear is a physical change, as it does not involve any chemical reactions. The gold bear retains its chemical identity while its physical shape is modified.
Sanding a piece of wood is also a physical change, as it only affects the surface of the wood by removing some material. The chemical composition of the wood remains the same.
Dissolving sugar in tea is a physical change, as it does not involve a chemical reaction. The sugar molecules disperse in the tea without altering their chemical structure.
The melting of a popsicle is a physical change, as it involves a change in the state of matter from solid to liquid. Since no new substances are formed, it is a physical change.
