Answer to Question 1

ANS: A
The velocity of gas molecules is directly proportional to temperature. As a gas is warmed, its ki-netic activity increases, its molecular collisions increase, and its pressure rises.

Answer to Question 2

ANS: D
Avogadro's law states that the 1-g atomic weight of any substance contains exactly the same number of atoms, molecules, or ions.
