This is what I said. It's logical since water's unique charateristic is that as a solid the molecules like to be farther apart (it is less dense)...and at higher temperatures, molecules speed up their movement and therefore spend time further apart. But how do you prove this?
This is what I said. This is obviously the key to the answer...but how/why? This is that makes WATER a UNIQUE molecule and therefore must have something to do with the reasoning behind the answer. It's not about just the temperature. It has to do with Physical Chemistry.
Old time engineer....getting the water to its freezing temperature IS NOT THE END GAME HERE. This is what you're talking about. The scientists are talking about it becoming a solid...this means a phase change AFTER the water is at its freezing temperature. It's not a straight line.
When molecules shift from one phase to another, the phase diagram is not a straight line. Getting to the temperature of freezing IS NOT THE END RESULT HERE. That's what you're arguing. It's the phase shift that the scientists are talking about....from liquid to solid. Once the temperature of the water reaches 32 degree...more
The key to the answer must have something to do with the UNIQUE characteristics of water...it's hydrogen bonding configuration. What does the phase diagram for water look like at different starting temperatures? At what temperature does this shift occur from "cold" water to "hot" water? How hot?
Sure...just ask religious people and they'll explain all the mysteries of the world to ya...cuz that's how God designed it. LOL!!
Water is the only molecule to EXPAND upon freezing because of the alignment of its hydrogen bonding. The molecules in HOT water are moving faster than the molecules in cold water...this ...more
