Question

What is the density of water vapour at boiling point of water?

Options

• 1 × 10^-4 g cm^-3

• 1 g cm^-3

• 6 × 10^-4 g cm^-3

• 4 × 10^-4 g cm^-3

Answer 1

6 × 10^-4 g cm^-3 

Explanation:

Water density varies with temperature, it never has an absolute value. The density of water vapour at 100°C (boiling point) is 6 × 10^-4 g cm^-3.
