Organic chemistry is the study of molecules containing carbon, so A
Answer: Option (A) is the correct answer.
Explanation:
When there occurs no change in the chemical composition of a substance then it is known as physical property.
For example, mass, volume, density are all physical properties.
Since, the mass of an electron is negligible and an electron holds a negative charge.
Therefore, negatively charged particle with very little mass accurately describes the physical properties of electrons in atoms.
The correct option is; SUGAR DISSOLVING IN WARM WATER.
There are two types of change in chemistry; physical and chemical changes.
A physical change is a type of change in which no new substance is formed while a chemical change is a type of change in which a new substance is formed.
Dissolving sugar in warm water is a physical change because no new substance is formed and the sugar can easily be recovered from the water by evaporating the water.
