Question

State Whether the following statements are True or False. Rewrite the correct statements :

1. Alcohol evaporates faster than ether.
2. Diffusion is faster in summer than in winter season.
3. Carbon dioxide has the largest molecular spaces.

Answer 1

1. False
Ether evaporates faster than alcohol because in case of alcohol the intermolecular force of attraction is stronger than ether. So it takes more energy to go into vapor phase.
2. True
Diffusion would be faster in the summer season because rate of diffusion is faster at higher temperature. The temperature of summer season is more than the winter season.
3. True
CO₂ is gas. And gases have largest intermolecular space as compared to solid and liquid.
