Interpretation:
Whether bromine is dense or air needs to be determined.
Concept introduction:
Density of a substance is defined as mass per unit volume.

Answer to Problem 96A
Bromine is denser than air.
Explanation of Solution
Bromine is denser than air because it doesn’t readily diffuse into air and takes time to mix thoroughly in air.
Interpretation:
Whether liquid bromine diffuses faster or gaseous bromine needs to be determined.
Concept introduction:
Bromine can exist in different states liquid or gaseous.

Answer to Problem 96A
Gaseous bromine diffuses quickly than liquid bromine.
Explanation of Solution
Diffusion is inversely proportional to density of substance. Density of liquid bromine is more than gaseous bromine. So, liquid bromine takes more time to diffuse than gaseous bromine.
