A particular material has a specific gravity of 1.04 at 20°C. As this material is heated from 20°C to 30°C, its volume increases faster than does the volume of water. Which of the following statements is true of the specific gravity of this material as it is heated to 30°C?
A) Its specific gravity decreases.
B) Its specific gravity increases.
C) Its specific gravity remains the same.
D) There is insufficient information to answer the question.

Quizplus · Accepted Answer

Specific gravity is the ratio of the density of a substance to the density of water at a particular temperature. As the material is heated, its volume increases faster than that of water, which means its density will decrease. Therefore, its specific gravity will decrease.
