Question: Which of the following is not an example of matter? (a) Chemical or Physical B) We have moderately strong evidence that the acceleration is real, but essentially no idea what is causing it. The polarity of water easily breaks the charges between the oppositely charged ions in the compound. Using a combination of lasers and magnets, Eric Cornell and Carl Weiman, scientists at the Joint Institute for Lab Astrophysics (JILA) in Boulder, Colorado, cooled a sample of rubidium to within a few degrees of absolute zero. This may occur either when the temperature of the sample is rapidly increased beyond the boiling point (flash vaporization) or when a substance is "freeze-dried" by cooling it under vacuum conditions so that the water in the substance undergoes sublimation and is removed from the sample, according to the U.S. Geological Survey (opens in new tab).
