The most familiar mixture of two immiscible liquids in everyday life are the vegetable oil and water in Italian salad dressing.
The volume of a quantity of liquid is fixed by its temperature and pressure.
Objects with chaotic rotations (such as Hyperion) are also problematic, as their synchronous orbits keep changing unpredictably.
Liquids in a gravitational field, like all fluids, exert pressure on the sides of a container as well as on anything within the liquid itself.
Liquids have little compressibility—water, for example, does not change its density appreciably unless subject to pressure of the order of hundreds bar.
Liquid components in a mixture can often be separated from one another via fractional distillation.
The surface temperature of a main sequence star is determined by the rate of energy production at the core and the radius of the star and is often estimated from the star's color index.
Only six elements are liquid at or near room temperature and pressure: bromine, mercury, francium, cesium, gallium and rubidium.
Liquids at their respective boiling point change to gases (except when superheating occurs), and at their freezing points, change to solids (except when supercooling occurs).
At a temperature below the boiling point, a liquid will evaporate until, if in a closed container, the concentration of the vapors belonging to the liquid reach an equilibrium partial pressure in the gas.
A liquid's shape is determined by, not confined to, the container it fills.
The main liquid found on Earth is water, which is essential to sustain life.
The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. 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.Jun 22, 2014
The molecules of liquids have a moderate force of attraction; the force between molecules is less than solids and more than gases. ... Liquids take the shape of the container they are stored in as the molecules move to fill the space. They have no definite shape and have the ability to flow.Feb 14, 2012
All liquids show the following characteristics:Liquids are almost incompressible. ... Liquids have fixed volume but no fixed shape.They have fixed volume but they do not have fixed or definite shape. ... Liquids flow from higher to lower level.Liquids have their boiling points above room temperature, under normal conditions.
Liquids take on the shape of their container. The liquid state of matter is an intermediate phase between solid and gas. Like the particles of a solid, particles in a liquid are subject to intermolecular attraction; however, liquid particles have more space between them, so they are not fixed in position.Jul 23, 2014
Examples of liquids are water at room temperature (approximately 20 ºC or 68 ºF), oil at room temperature, and alcohol at room temperature. When a liquid is heated, the atoms or molecules gain kinetic energy . ... Water is an example of a liquid that becomes gaseous when it is heated gradually.
Many people believe that the visible plume of steam from a boiling kettle is water vapor. However, the steam that you see consists of very small water droplets suspended in the air, while water vapor is the invisible gas that results when water evaporates.
Earth's inner core is solid: Official. The core of the Earth is made up mainly of iron, in an outer liquid layer and an inner solid layer. The outer core is where the circulating conducting liquid generates the geodynamo, responsible for our magnetic field.Oct 1, 2008
Liquid nitrogen is nitrogen in a liquid state at an extremely low temperature. It is a colorless clear liquid with a density of 0.807 g/ml at its boiling point (−195.79 °C (77 K; −320 °F)) and a dielectric constant of 1.43.
Answer 1: Earth´s inner core and outer core are both made of an iron-nickel alloy. The state of matter (solid, liquid or gas) of a given material depends on its temperature and pressure. Most materials, including iron and nickel, change from liquid to solid at lower temperatures and/or higher pressures.
The outer core of the Earth is a fluid layer about 2,300 km (1,400 mi) thick and composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. Its outer boundary lies 2,890 km (1,800 mi) beneath Earth's surface.
Earth's inner core is solid: Official. The core of the Earth is made up mainly of iron, in an outer liquid layer and an inner solid layer. The outer core is where the circulating conducting liquid generates the geodynamo, responsible for our magnetic field.Oct 1, 2008
The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth's structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.May 20, 2015
Saturn is almost entirely hydrogen and helium, but it does have trace amounts of other chemicals, including water. When we look at Saturn, we're actually seeing the upper cloud tops of Saturn's atmosphere. ... For example, Saturn's moon Enceladus is thought to have a mantle rich in water ice, surrounding a silicate core.Jul 3, 2008
