Which state of matter shows the highest expansion when temperature is increased?
-
A.
Liquids
-
B.
Solids
-
C.
Plasma
-
D.
Gases
Correct Answer:
D. Gases
Explanation:
Gases exhibit the most significant expansion when their temperature rises because their particles are far apart and have negligible intermolecular forces compared to solids and liquids. This lack of strong attraction allows gas molecules to move more freely and occupy a much larger volume as their kinetic energy increases. In contrast, particles in solids and liquids are more tightly packed and held together by stronger bonds, which restricts their ability to expand significantly. Therefore, among the states of matter, gases demonstrate the highest coefficient of thermal expansion.
