Consider the following statements: 1. Matter is defined as anything that has mass but does not occupy space. 2. The smell of perfume is matter, but the feeling of love is not. 3. Air is not considered matter because it cannot be seen. Which of the statements given above is/are correct?

Correct Option The correct option is (b). Explanation Matter is scientifically defined as anything that possesses mass and occupies space (volume). All physical substances, regardless of their state (solid, liquid, or gas) or visibility, are classified as matter. Statement-wise Analysis: - Statement 1 is Incorrect: The fundamental definition of matter requires two simultaneous conditions: it must have mass and it must occupy space. The statement incorrectly asserts that matter does not occupy space. - Statement 2 is Correct: The "smell" of perfume is perceived due to the presence of volatile chemical particles diffusing through the air. Since these particles have mass and occupy space, they are matter. In contrast, "love" is an abstract emotion; it possesses neither mass nor volume and is therefore not matter. - Statement 3 is Incorrect: Air is a physical mixture of gases. Despite being generally invisible to the naked eye, air has mass and occupies space (demonstrated when inflating a balloon). Visibility is not a prerequisite for a substance to be classified as matter. Key Takeaway: To be classified as matter, an entity must have both mass and volume. Abstract concepts (emotions, thoughts) and forms of energy (light, sound) do not meet these criteria.

Solution

Correct Option

The correct option is (b).

Explanation

Matter is scientifically defined as anything that possesses mass and occupies space (volume). All physical substances, regardless of their state (solid, liquid, or gas) or visibility, are classified as matter.

Statement-wise Analysis:

Statement 1 is Incorrect: The fundamental definition of matter requires two simultaneous conditions: it must have mass and it must occupy space. The statement incorrectly asserts that matter does not occupy space.
Statement 2 is Correct: The "smell" of perfume is perceived due to the presence of volatile chemical particles diffusing through the air. Since these particles have mass and occupy space, they are matter. In contrast, "love" is an abstract emotion; it possesses neither mass nor volume and is therefore not matter.
Statement 3 is Incorrect: Air is a physical mixture of gases. Despite being generally invisible to the naked eye, air has mass and occupies space (demonstrated when inflating a balloon). Visibility is not a prerequisite for a substance to be classified as matter.

Key Takeaway:

To be classified as matter, an entity must have both mass and volume. Abstract concepts (emotions, thoughts) and forms of energy (light, sound) do not meet these criteria.
