Which of the following represents the correct order of arrangement?

• A. Water, air , wind
• B. Air, sugar, oil
• C. Oxygen,water, piece of iron
• D. Salt, juice, air

Answer 1

The correct option is C

Oxygen,water, piece of iron

• In a solid, a particle can vibrate but it can not move. piece of iron is solid.
• In liquid the force of attraction is weaker than in solid. water is liquid.
• In gas, the particle moves fast in a random direction so there is no force of attraction. Oxygen is a gas.
• Oxygen, water, and a piece of iron is the correct order.
• Hence option C is correct.
