Question

2. a substance in the gas state has a density about times less than when it is in the liquid state. the diameter of a molecule is . what is the best estimate of the average distance between molecules in the gas state? a. b. c. d. 1000 d d 10d 100d 1000d

Answer 1

In gases, the distance between molecules is about 10 times greater than the size of their molecules, resulting in lower densities.

Step-by-step explanation:

Atoms and molecules are close together in solids and liquids. In gases, they are separated by empty space, resulting in lower densities. The density of a substance is mass per unit volume, and volume is related to the size of the molecules. When the distance between molecules in gases increases by a factor of 10, the volume occupied increases by a factor of 1000, and the density decreases by a factor of 1000.
