Answers
Answer:
The two groups for the classification will be the groups of physical and chemical change. A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity.
Explanation:
1. A fruit falling from a tree will be considered a physical change as there is no chemical reaction involved in the process.
2. Rusting of iron will be classified under the chemical change as process of rusting occurs due to the chemical reaction between iron and oxygen.
3. Raining will be classified under the category of physical change as the chemical composition of water is remaining the same. Only the state of water changes when the water rotates in the water cycle.
4. Lightning of an electric bulb is also a physical change because as the electricity is passed through the tungsten, it glows, no chemical process occurs during the process.
5. Cutting vegetables is also considered a physical change as the cutting of vegetables only changes the shape of the vegetables.
