Passage IV
When substances are heated, they typically expand (increase in volume). Under certain circumstances, some substances will contract (decrease in volume) when heated. Table 1 shows the change in volume that occurred when 1.0000 L samples of solids at different initial temperatures were heated. Tables 2 and 3 show the results for similar trials using 1.0000 L samples of liquids and gases, respectively.
(Note: No phase changes occurred in any of the trials, and the gas samples were heated at constant pressure.)
20. Based on Table 1, if a 1.0000 L sample of lead at 24°C is cooled to 14°C, the volume will most likely:
Your Answer is
Correct Answer is F
Explanation
When the lead in table 1 is heated from 14°C to 24°C, the volume should increase by 0.0009 L. Then, if the temperature is lowered from 24°C to 14°C, the volume should be reduced by 0.0009L (heat expansion and contraction)
