  • d)
    All are correct
Correct answer is option 'A'. Can you explain this answer?

Rounak Chawla answered
Explanation:

I. Water boils at 100 degrees Celsius at sea level:
- This statement is correct. Water boils at 100 degrees Celsius at sea level. As the altitude increases, the boiling point of water decreases.

II. The human body has four lungs:
- This statement is incorrect. The human body typically has two lungs, not four. Lungs are vital organs responsible for breathing and oxygenating the blood.

III. The Amazon Rainforest is located in South America:
- This statement is correct. The Amazon Rainforest is indeed located in South America, primarily in countries such as Brazil, Peru, Colombia, and Venezuela. It is the largest tropical rainforest in the world.

IV. The Moon is a planet:
- This statement is incorrect. The Moon is not a planet; it is a natural satellite that orbits around the Earth. Planets, such as Earth, Mars, and Jupiter, revolve around the Sun.
Therefore, the correct statements are I and III only, making option 'A' the correct answer.

Identify the correct scientific statements.
(i) The chemical symbol for gold is ___________.
(ii) Water freezes at ___________ degrees Celsius.
(iii) The speed of light is approximately ___________ km/s.
  • a)
    Au, 0, 300,000
  • b)
    Ag, 32, 150,000
  • c)
    Fe, -100, 1,000
  • d)
    Cu, 10, 500,000
Correct answer is option 'A'. Can you explain this answer?

Pranjal Gupta answered
The Chemical Symbol for Gold
Gold is a precious metal known for its distinctive yellow color and high malleability. The correct chemical symbol for gold is:
- Au (from the Latin word "Aurum")
This confirms the first statement in the question.
Water Freezing Point
Water is essential for life and has unique properties. It freezes at:
- 0 degrees Celsius
This satisfies the second statement in the question.
The Speed of Light
The speed of light is a fundamental constant in physics. It travels at approximately:
- 300,000 km/s
This completes the third statement in the question.
Analysis of Options
Let's analyze the provided options:
- a) Au, 0, 300,000: Correct for all three statements.
- b) Ag, 32, 150,000: Incorrect; Ag is silver, and water freezes at 0°C, not 32°C.
- c) Fe, -100, 1,000: Incorrect; Fe is iron, and the freezing point is not -100°C, and the speed of light is much higher than 1,000 km/s.
- d) Cu, 10, 500,000: Incorrect; Cu is copper, and the freezing point and speed of light are inaccurately represented.
Conclusion
Therefore, the correct answer is option A: Au, 0, 300,000, as it accurately reflects the chemical symbol for gold, the freezing point of water, and the speed of light.
