Which all substances show anomalous expansion?

Among the substances showing anomalous properties in the liquid phase we find silica (SIO2) [1–3], silicon (Si) [4,5], selenium (Se) [6], phosphorus (P) [7–9] and water [10].

Which substance exhibits an anomalous expansion when heated?

water
The anomalous expansion of water is an abnormal property of water whereby it expands instead of contracting when the temperature goes from 4o C to 0o C, and it becomes less dense.

Does Silicon show anomalous expansion?

Actually, yes. It is not common, but it happens that Bismuth, Antimony, Germanium, Silicon, and Gallium all expand on solidification.

Which metals show anomalous Behaviour as water does?

Antimony shows anomalous behavior. It too is less dense than the liquid at the freezing point.

What is the reason for anomalous behaviour of water?

The anomalous behavior of water, sometimes called the density anomaly, is due to strong intermolecular attractions between water molecules called hydrogen bonds. The large electronegativity difference between oxygen and hydrogen causes the hydrogen-oxygen bonds to be polar.

What is the cause of anomalous behaviour of water?

What is the anomaly of water?

anomalous
Water is unique in its number of unusual, often called anomalous, properties. When hot it is a normal simple liquid; however, close to ambient temperatures properties, such as the compressibility, begin to deviate and do so increasingly on further cooling.

What is an anomalous behavior?

Anomalous behavior is the unique behavior of the element with respect to other elements of the same group. It’s unique properties are anomalous properties.

What is the cause of anomalous expansion of water?

Hydrogen bond is responsible for the anomalous expansion of water below 4C. Hydrogen bonds actually keep water molecules at a greater distance from each other than when there’s no such bond at higher energy levels, i.e. higher temperatures when it’s a liquid.

What is the reason of anomalous behavior of water?

What are anomalous properties in the liquid phase?

Among the substances that present anomalous properties in the liquid phase, we find silica (SIO2), silicon (Si), selenium (Se), phosphorus (P) and water. For water, and also for these substances, TMD means an anomaly in the thermodynamic response function.

What is the meaning of anomalous property of water?

Anomalous (adj.) -deviating from what is standard, normal, or expected. Now by the question, one can assume that water shows such properties that is NOT expected. You did specify particular for which property water shows anomaly whereas Water show a wide range of anomalies compared to similar liquids or hydrides of other group 16 elements.

What are the applications of anomalous expansion of water?

Between a certain range of temperatures, it shows anomalous expansion of water which has many applications. This helps in the survival of marine life, this is one of the major importance of this behaviour of water, and there are many applications which are discussed. Generally, on heating water it expands and on cooling it contracts.

What is the importance of the behaviour of water?

Water shows the un-natural behaviour which makes it unique. Between a certain range of temperatures, it shows anomalous expansion of water which has many applications. This helps in the survival of marine life, this is one of the major importance of this behaviour of water, and there are many applications which are discussed.
