Chemistry
Which of the following substances has the largest intermolecular spaces?
- A piece of iron metal
- A glass of water
- A spoon of common salt
- A balloon filled with hydrogen gas
Answer
A balloon filled with hydrogen gas
Reason — Gases have the largest intermolecular spaces compared to solids and liquids. In a gas like hydrogen, the molecules are far apart and move freely, resulting in much larger intermolecular spaces.
Particles are very tightly packed in a piece of iron metal and have very small intermolecular space. Particles are less tightly packed than solids in a glass of water and have moderate intermolecular space. Particles are closely packed in a spoon of common salt and have very small intermolecular space.
