In one of the following options, materials are arranged in increasing order of the force of attraction between their particles. Choose the correct option:
- AHydrogen gas, water, iron metal
- BAir, salt, juice
- CSalt, juice, air
- DNone of the above
Show answer and explanation
Correct answer: (a) Hydrogen gas, water, iron metal
Explanation
The attraction between particles is weakest in gases, stronger in liquids and strongest in solids.
So hydrogen gas → water (liquid) → iron metal (solid) is in increasing order. In the other options, air (a gas) or juice (a liquid) is out of place.
