Why does liquids expand when frozen




















It is because ice is of lesser density than water due to the reason mentioned above. Your email address will not be published. Save my name, email, and website in this browser for the next time I comment. All rights reserved. Reproduction in whole or in part without permission is prohibited.

Ice has a lesser density than water. The Molecular Standpoint The water molecule , consisting of 2 atoms of hydrogen and one of oxygen forms a Mickey Mouse head-like structure such that the ears are the hydrogen atoms and the head is represented by the oxygen atom.

Is every snowflake unique? Comments erm Thanks, but OP is correct, only a child would be satisfied with that! Quote from the article: "When water freezes, the molecules get themselves into the most stable configurations or positions that have the minimum amount of energy in the resulting ice crystal. Sorry, I made an error in wording.

The density reaches a maximum, not a minimum, at 4 deg C. How great this website is! This is a great website very good at describing why water expands when it freezes. Last lines are not clear can you please explain them in a different way. Thanks you for that. No, that is not accurate Ummm, that doesn't really explain anything The last sentence explains almost nothing Thank you for highlighting that; I've altered the wording slightly to improve the clarity.

Not quite That's correct. I love ur explanations they are good. I love your explanation. They are very clear. Thank you,I exactly got what Thank you,I exactly got what i needed to know. Your name. Leave this field blank. Support Us! Make a donation to support the Naked Scientists.

The liquid contracts as it is cooled; because the molecules are moving slower they are less able to overcome the attractive intermolecular forces drawing them closer to each other. Then the freezing temperature is reached, and the substance solidifies, which causes it to contract some more because crystalline solids are usually tightly packed.

Water is one of the few exceptions to this behavior. When liquid water is cooled, it contracts like one would expect until a temperature of approximately 4 degrees Celsius is reached. This unusual behavior has its origin in the structure of the water molecule. There is a strong tendency to form a network of hydrogen bonds, where each hydrogen atom is in a line between two oxygen atoms.
