Question

As water freezes ______. as water freezes ______. its hydrogen bonds break apart its molecules move farther apart it cools the surrounding environment it absorbs energy from the surrounding environment it loses its polarity

Answer 1

Answer: Option (a) is the correct answer.

Explanation:

Usually when freezing occurs then molecules of a substance come closer to each other. But there is an exception with water because when temperature of water reaches at less than 4 degree celsius then its atoms start to move apart from each other.

As a result, there occurs a breakage of hydrogen bonding. Due to this volume of ice increases and hence, there will be decrease in its density. This also make ice to float on water.

Thus, we can conclude that as water freezes its hydrogen bonds break apart.

Answer 2

As water freezes its molecules move farther apart. As when water freezes , Its move farther apart .

And the cause of this movement is hydrogen bond that is formed among the surrounding water molecules that causes water molecules to move apart. So as water freezes its molecules move farther apart, it is the correct answer .
