physical change, because the frozen rain can be turned back into rain (or water if you want to be exact) But a good example of a chemical reaction would be, you have the ingredients for a cake, you take those ingredients, mix and bake them, that would be a chemical reaction because it cannot be turned back into a cake
Is lighting a Bunsen burner a chemical reaction?
Yes, because a gas is burned - an oxydation reaction. This chemical reaction produces heat as well as carbon dioxide and water vapor as products from methane and oxygen gas. The heat also excites the electrons in the gases it produces, causing them to gain energy and rapidly emit this energy in the form of photons predominately with a wavelength of approximately 475 nm, which we perceive as blue light. The reaction can be described by the following equation: CH4 (g) + 2 O2 (g) => CO2 (g) + 2 H2O (g)
