Question

What is the approximate interatomic spacing in gases at NTP (Normal Temperature and Pressure)?

विकल्प

• 10⁻¹² m

• 10⁻¹⁰ m

• 10⁻⁹ m

• 10⁻⁷ m

Answer 1

10⁻⁹ m

Explanation:

At NTP, the interatomic spacing in gases is approximately 10⁻⁹ m, which is about 10 times larger than in solids (approximately 10⁻¹⁰ m). This large spacing explains why gases are highly compressible and have no definite shape or volume.
