What are 2 chemical changes?

Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding. Many physical changes are reversible, if sufficient energy is supplied. The only way to reverse a chemical change is via another chemical reaction.

Which are physical and which are chemical changes?

  • Changes around us • Changes can be classified in: 1. Slow and fast 2.
  • Physical Changes • Changes that involve a change in only the physical properties of a substance and where no new substance is formed are called Physical change.
  • What can indicate a physical or chemical change?

    Physical and Chemical Changes. An observation that indicates a physical change is a change of physical state. The observations that suggest a chemical change include burning, fizzing, changing color, or forming an insoluble substance in solution. (a) Hydrogen explodes; thus, it is a . chemical. change. (b) Water is boiled; thus, it is a
