Zirconium Tungstate Is an Unusual Material Because Its Volume Shrinks $\Delta$

question 25

Multiple Choice

Zirconium tungstate is an unusual material because its volume shrinks with an increase in temperature for the temperature range 0.3 K to 1050 K (where it decomposes) . In fact, the volumetric coefficient of thermal expansion is -26.4 × 10^-6/K. Determine the ratio $\Delta$ V/V₀ for the above mentioned temperature range. Express your answer in percent.

• A)-5.28%
• B)-3.59%
• C)-2.77%
• D)-1.90%
• E)-1.04%
