The process of heating coal in the absence of air to produce coal gas, coal tar, and coke is called:
A. Fractional distillation
B. Cracking
C. Destructive distillation
D. Carbonization
Answer: Option C
Solution (By JKExamLibrary)
Destructive distillation is the process of heating a carbon-containing substance (like coal or wood) in the absence of air to break it down into various products. For coal, it yields coke, coal tar, coal gas, and coal dust. Fractional distillation is used for separating liquid mixtures like petroleum.

Question #3
Which of the following is a characteristic of a physical change?
A. Change in chemical composition
B. Easily reversible, no new substance
C. Irreversible and energy change
D. Formation of new substance

Correct Answer: Option B


Explanation:
Physical changes alter the form, state, or appearance without changing chemical identity. They are usually easily reversible (e.g., freezing/melting). Chemical changes produce new substances and are often irreversible (e.g., burning). Physical: crushing, dissolving, boiling. Chemical: rusting, cooking, digestion.
