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 δv/v0 for the above mentioned temperature range. express your answer in percent.

Argon, neon, and xenon are examples of
