**Correct Statements About Water**
Water is a fundamental substance that plays a crucial role in the existence of life on Earth. Let's explore the correct statements about water based on the provided options.
- **Freezing and Boiling Points**
- **Correct Statement:** Water freezes at 0 degrees Celsius.
- This statement is correct. When the temperature of water reaches 0 degrees Celsius, it changes from a liquid state to a solid state, forming ice.
- **Incorrect Statement:** Water boils at 90 degrees Celsius.
- This statement is incorrect. Water boils at 100 degrees Celsius. When the temperature reaches this point, water changes from a liquid state to a gaseous state.
- **Composition of Water**
- **Correct Statement:** Water is a compound made of hydrogen and oxygen.
- This statement is correct. The chemical formula for water is H2O, indicating that each water molecule consists of two hydrogen atoms bonded to one oxygen atom.
- **Incorrect Statement:** Water is an element.
- This statement is incorrect. Water is not an element but a compound composed of two different elements, hydrogen and oxygen.
Therefore, the correct statements about water are:
- (i) Water freezes at 0 degrees Celsius.
- (iii) Water is a compound made of hydrogen and oxygen.
These statements accurately describe key properties and characteristics of water, highlighting its importance in various natural processes and human activities.

Understanding the Incorrect Statements about Magnets
When evaluating the provided statements about magnets, it’s essential to clarify the properties of magnets.
Statement Analysis
- Statement (i): Magnets have two poles, north and south.
- This statement is correct. All magnets have a north pole and a south pole.
- Statement (ii): Like poles attract each other.
- This statement is incorrect. Like poles (north-north or south-south) actually repel each other, while opposite poles (north-south) attract.
- Statement (iii): Magnets can attract only metals.
- This statement is also incorrect. While magnets primarily attract ferromagnetic materials like iron, nickel, and cobalt, they can also influence other materials under certain conditions (e.g., paramagnetic materials).
- Statement (iv): Opposite poles repel each other.
- This statement is incorrect. Opposite poles attract each other, while like poles repel.
Conclusion
Based on the analysis:
- The incorrect statements are (ii) and (iii).
- Therefore, the correct answer is option 'B': (ii) and (iii) only.
This understanding of magnetic properties is fundamental for grasping how magnets interact with each other and with various materials in our environment. Always remember that opposite poles attract, and like poles repel!

Water expands when it freezes:
- True (T)
- When water freezes, it forms a crystalline structure which causes it to expand, unlike most substances which contract when they solidify.
The speed of light is faster than the speed of sound:
- True (T)
- Light travels at a speed of approximately 299,792 kilometers per second, which is much faster than the speed of sound in air, which is about 343 meters per second.
Sugar is a complex carbohydrate:
- False (F)
- Sugar is a simple carbohydrate, not a complex one. Complex carbohydrates are made up of multiple sugar molecules linked together, while simple carbohydrates consist of one or two sugar molecules.
The Amazon River is the longest river in the world:
- False (F)
- The Nile River in Africa is actually the longest river in the world, with a length of about 6,650 kilometers, while the Amazon River in South America is the second longest.

Jithin Chakraborty answered |
Root Photosynthesis:
Roots are the part of the plant that absorbs water and nutrients from the soil. However, photosynthesis, the process by which plants make their food using sunlight, primarily occurs in the leaves. This means that roots do not typically engage in photosynthesis.
Explanation of the correct answer (Option A):
Option A, "Root Photosynthesis," is an incorrect pairing of terms. Photosynthesis occurs in the leaves of plants, not in the roots. The roots' main function is to absorb water and nutrients from the soil, which are then transported to the rest of the plant for use in processes like photosynthesis. Therefore, the correct pairing would be "Leaf Photosynthesis" instead of "Root Photosynthesis."
