In summary, the anomalous behavior of water refers to its unique properties such as large specific heat, expansion while freezing, and hydrogen bonding. These properties are a result of the molecular structure and behavior of water molecules. The temperature range at which these phenomena occur cannot be changed by any means. Hydrogen bonding is the key factor in causing water to behave differently than other liquids.

What is the exact scientific reason behind anamalous behavour of water?
Can the temperature range at which this happens be changed?
do any other substances also behave anamalously?

mmm...what's anomalous?
 
  • #3
No, no, the OP clearly said anamalous, whatever that is.
 
  • #4
He did say anamalous but that was probably just a typing error. He meant to write anomalous.
 
  • #5
He wrote anamalous three times, it is not a typo.

To OP: please elaborate. In most cases water behaves as every other liquid. Sometimes it doesn't, but you need to explain what you mean if you want to get any help.

Besides, it looks like a HW question to me...

Sorry for typing mistake.
I meant ' anomalous' only.
It's not a HW question.
 
  • #7
So what are you talking about Sourabh?
Large specific heat, expansion while freezing, inertness, or something else?
 
  • #8
The weird behaviour at 4 C to 0 C .

Well, water is composed of three atoms two hydrogen and one oxygen. So a molecule looks likes this:

-When the temperature decreases the molecules start slowing down.
-This causes the volume to decrease and density to increase until 4°C while its still in liquid state.
-After this the molecules start crystallizing in a cage like structure by hydrogen bonding. Hydrogen bonding is a weak molecular interaction between the oxygen of one molecule and Hydrogen of another.
-In the crystallization process the density decreases and volume increases as the H-bonds push molecules apart to maintain a stable crystal lattice.
-The differences can be seen in this image [left is liquid and right is ice]:

Bond... hydrogen bond.
Shaken, not stirred.

Nooo, supercool it and then shake it! The drink shall turn to Ice cream...

The actual drink is a Vesper martini, it went like this:
"A dry martini," Bond said. "One. In a deep champagne goblet."
"Oui, monsieur."
"Just a moment. Three measures of Gordon's, one of vodka, half a measure of Kina Lillet. Shake it very well until it's ice-cold, then add a large thin slice of lemon peel. Got it?"

Thank you for such agood description.
My next query is "can the temperature range at which this phenomena occurs be changed by any means?"
 

1. What is the cause of water's anomalous behavior?

The cause of water's anomalous behavior is its unique molecular structure. The hydrogen bonds between water molecules create a network that allows for various anomalies, such as its high surface tension and density maximum at 4°C.

2. How does water's anomalous behavior affect living organisms?

Water's anomalous behavior plays a crucial role in the survival of living organisms. For example, its high surface tension allows for capillary action, which is essential for water transport in plants. The density maximum at 4°C also allows for bodies of water to remain liquid at the bottom, providing a habitat for aquatic organisms.

3. Can water's anomalous behavior be observed in everyday life?

Yes, many of water's anomalous properties can be observed in everyday life. For instance, the fact that ice floats on water is due to its lower density, which is a result of its unique molecular structure. Water's high surface tension can also be seen when droplets of water form on surfaces rather than spreading out.

4. Are there any practical applications of water's anomalous behavior?

Water's anomalous behavior has several practical applications, especially in industries such as agriculture, biology, and materials science. For example, its high surface tension is utilized in capillary tubes for blood tests, and its density maximum is important for the survival of aquatic animals during winter.

5. Can water's anomalous behavior be altered or controlled?

While water's anomalous behavior cannot be altered, it can be controlled to some extent through external factors such as pressure and temperature. For instance, pressure can affect the density of water, and temperature can influence its boiling and freezing points. However, the underlying molecular structure of water remains unchanged.
