Hence ripening of fruits is a chemical change. Growing a tree from a plant is an irreversible change which is accompanied by change in chemical composition.How do you know that rusting of iron is a change? If a raw egg is boiled in water, what changes do you notice in it ? Explain.When electricity is passed through the bulb (tungsten ) the electrons in the atoms get excited and release the energy as light in terms of photons. So no chemical reaction is taking place. It is physical reaction.Choose incorrect statements from the following and rewrite them correctly:An electric bulb going on and off is a permanent change.Choose incorrect statements from the following and rewrite them correctly:An electric bulb going on and off is a permanent change.When electricity is passed through the bulb (tungsten ) the electrons in the atoms get excited and release the energy as light in terms of photons.
