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.
microwaves are so quick and efficient because they channel heat energy directly to the molecules (tiny particles) inside food. microwaves heat food like the sun heats your face—by radiation.
well a basic explanation is that some elements have enough electrons to be considered stable. these elements do not need to react with other elements to gain more electrons. reactive elements are no where near stable; they respond with other elements in order to become stable. the more unstable, the harsher the reaction is.
most likely, the equation is
acceleration over a period of time =
(change in speed during the period of time)
(length of the period of time) .
