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 times 10 – 6 K. Determine the ratio V/V0 for the above mentioned temperature range. Express your answer in percent. – 5.28% – 3.59% – 2.77% – 1.90% – 1.04% I tried using the Delta L = ~ L Delta T formula. This went into the formula – 26.4 times 10 – 6( 1049.7), and ended up with – 2.77%, which was wrong. What was my error?
