Question

Evidence that a gas consists mostly of empty space is the fact that: (A) the density of a gas becomes much greater when it is liquefied (B) gases exert pressure on the walls of their containers (C) gases are transparent (D) heating a gas increases the molecular motion (E) nature abhors a vacuum

Answer 1

(A) the density of a gas becomes much greater when it is liquefied

Step-by-step explanation:

The gaseous state is composed of mainly empty space , therefore , the density of the gas increases as it goes to the liquid phase .

As , in the liquid state , the molecules are close together , there by increasing the density of the liquid state .

There fore , from the options , the most appropriate is option a.
