Question

Which points will you consider while classify the following changes into two groups of fruit falling from a tree rusting of iron raining lightning an electric bulb cutting vegetables

Answer 1

The changes into two groups of fruit falling from a tree

Explanation:

The groups of physical and chemical change will be the two groups for classification. A chemical change is the result of a chemical reaction, whereas a physical change is when the shape of matter changes, but not the chemically  

1. As there is no chemical reaction involved in the process, a fruit falling from a tree would be labeled as a physical change.  

2. Iron rusting will be labeled as a chemical change due to the chemical reaction between iron and oxygen as the rusting process occurs.  

3. Raining should be categorized underneath the physical change classification as the water's chemical composition remains the same. Only when the water rotates in the water cycle, the state of water changes.  

4. An electric bulb lightning is also a physical change because as the electricity passes through the tungsten, it glows, there is no chemical process during the process.

5. Cutting vegetables is also considered a physical change as vegetable cutting only changes the vegetables ' shape.
