-
A.
Plasma
-
B.
Liquids
-
C.
Solids
-
D.
Gases
Correct Answer:
D. Gases
Explanation:
Gases exhibit the most significant expansion when heated because their molecules are far apart and held by very weak intermolecular forces. As temperature rises, the kinetic energy of these particles increases, causing them to move more rapidly and spread out extensively to fill any available space. This behavior is described by the Ideal Gas Law, which shows that a gas's volume is directly proportional to its absolute temperature. In contrast, the tightly packed particles in solids and liquids are constrained by stronger bonds, resulting in much lower rates of thermal expansion.
