AP SSC Physical Science Paper Answer Key 2025
SECTION – I
1. Predict and write why the preparation of lime water is considered an exothermic reaction.
Ans: The preparation of lime water involves the dissolution of quicklime (CaO) in water, forming slaked lime (Ca(OH)₂). This reaction releases heat, making it an exothermic reaction.
2. Acidic nature of a substance is due to the formation of __________ ions in solution.
Ans: Acidic nature of a substance is due to the formation of hydrogen (H⁺) ions in solution.
3. Observe the following table:
| Substance | Lemon juice | Blood | Milk of magnesia |
|---|---|---|---|
| pH value | 2.2 | 7.4 | 10 |
In the above table, which is the strong acid?
Ans: Lemon juice is the strongest acid because it has the lowest pH value (2.2), indicating high acidity.
4. Which is the most ductile metal in nature?
Ans: Gold (Au) is the most ductile metal in nature. It can be drawn into extremely thin wires without breaking.
5. Write any one use of vinegar.
Ans: Vinegar is used as a preservative in pickles and food items.
6. The human eye forms the image of an object at its ______.
a) Cornea
b) Iris
c) Pupil
d) Retina
Answer: (d) Retina
7. Draw the symbol of an Ammeter.
Ans: The symbol of an ammeter is Ⓐ (a circle with the letter 'A' inside it).
8. What is the commercial unit of electric energy?
Ans: The commercial unit of electric energy is Kilowatt-hour (kWh).
SECTION – II
9. Fill the table:
| Class of Compounds | Formula of Functional Group |
|---|---|
| Alcohol | -OH (Hydroxyl group) |
| Carboxylic Acid | -COOH (Carboxyl group) |
10. Frame any two questions to understand the concept of refraction.
-
What happens to the direction of light when it travels from air to water?
-
Why does a pencil appear bent when partially immersed in water?
11. Predict and write why tungsten is used as a filament in electric lamps.
Ans: Tungsten is used as a filament in electric lamps because:
-
It has a high melting point (about 3,422°C), allowing it to withstand high temperatures without melting.
-
It has high electrical resistance, which helps it glow brightly when an electric current passes through it.
