Which of the following statements is true regarding temperature changes and expansion?

The statement regarding the coefficients of expansion for liquids changing in value as the temperature changes is true.

As temperature increases, the kinetic energy of the molecules in a liquid also increases, leading to greater molecular movement and spacing. This results in an increase in volume, or thermal expansion. However, the rate of expansion is not constant across all temperatures. Each liquid has a specific coefficient of thermal expansion that varies with temperature, which means that as the temperature changes, the value of that coefficient will also change. Understanding this concept is crucial for applications involving temperature variations, as it allows for accurate calculations in systems where thermal expansion must be accounted for, such as in pipelines, storage tanks, and other components in engineering systems.

The other options do not hold true in the same way. Water, for instance, has unique properties that allow it to expand upon freezing, which contradicts the claim in the first statement. The second statement incorrectly implies that all liquids behave the same way when cooled, which is not accurate as many liquids do contract upon cooling. Lastly, while solids do generally have lower coefficients of thermal expansion compared to liquids, stating that solids have greater coefficients without distinction can be misleading, especially considering that there are exceptions depending on the materials in question.
