Question

a fruit (6) Which points will you consider while classifying the following changes into two groups a fruit falling from a tree, rusting of iron, raining, lighting an electric bulb, cutting vegetables?​

Answer 1

Answer:

The two groups for the classification will be the groups of physical and chemical change. A chemical change results from a chemical reaction and change in chemical identity, while a physical change is when matter changes forms but not chemical identity.

1. A fruit falling from a tree will be considered a physical change.
2. Rusting of iron will be classified under the chemical change.
3. Raining will be classified under the category of physical change.
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.
