What is one unusual property of water?
Unique properties of water Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen, and a bent overall structure. This is because oxygen is more electronegative, meaning that it is better than hydrogen at attracting electrons. Water is an excellent solvent.
What are 3 properties of liquid?
All liquids show the following characteristics:
- Liquids are almost incompressible. In liquids molecules are pretty close to each other.
- Liquids have fixed volume but no fixed shape.
- Liquids flow from higher to lower level.
- Liquids have their boiling points above room temperature, under normal conditions.
What are 4 unusual properties of water?
Because water seems so ubiquitous, many people are unaware of the unusual and unique properties of water, including:
- Boiling Point and Freezing Point.
- Surface Tension, Heat of Vaporization, and Vapor Pressure.
- Viscosity and Cohesion.
- Solid State.
- Liquid State.
- Gas State.
What can gases do?
Gas. The atoms and molecules in gases are much more spread out than in solids or liquids. A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid.
Which is a unique property of a liquid?
We now turn our attention to three unique properties of liquids that intimately depend on the nature of intermolecular interactions: surface tension, capillary action, and viscosity. Surface Tension We stated in Section 11.1 “The Kinetic Molecular Description of Liquids”that liquids tend to adopt the shapes of their containers.
Why does a liquid have no definite shape?
A liquid has no definite shape and acquires the shape of the container. It can flow from a higher lever to a lower level. Reason: Intermolecular force of attraction is weaker in a liquid than in a solid. Liquid molecules can move, slip and slide over each other because their molecular separation is larger.
Why does a liquid have a definite volume?
1. A liquid has a definite volume. Reason: Intermolecular force of attraction is just strong enough to confine the molecules in a definite space. 2. A liquid has no definite shape and acquires the shape of the container. It can flow from a higher lever to a lower level.
How are the properties of a liquid related to its temperature?
Temperature related properties of liquids include boiling point, which is the temperature at which the liquid begins to evaporate or convert to a gas. The freezing point is the temperature at which the liquid begins to turn to a solid. Each pure liquid will have its own specific boiling and freezing points.
