A second feature of H2O molecules is that they behave differently from most molecule when heated or cooled.
Most materials expand when heated and contract when
cooled. Water contracts when cooled until reaches 4°C.
(Water freezes at 0° Celsius.) As it continues to cool, water
reverses and begins to expand.

what is the comparison inherent in this paragraph?

A. At freezing , h2O molecules expand rather than contract as most molecules .

B. H2O molecules behave different from other molecules.

C. Most molecules expand when heater & contract when cooled .

explanation:

crosscutting concepts have application across all domains of science. as such, they are a way of linking the different domains of science. they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.

thats a little if u want the answer just look it up on google thats what i do haha : )

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?
