The surface energy of a solid is usually measured at high temperatures.

This can be at the surface or at the bottom.

The atmospheric mass is 93 times that of Earth's atmosphere, whereas the pressure at the planet's surface is about 92 times that at Earth's surface a pressure equivalent to that at a depth of nearly 1 kilometre under Earth's oceans.

Similar to surface tension, adsorption is a consequence of surface energy.

Shallow ponds often have a continuous temperature gradient from warmer waters at the surface to cooler waters at the bottom.

Parts and components of liquid propellant surface to air missiles can also be reused in a surface to surface role, like the liquid propellant engines of the SA 2 missiles used in the Samoud 2 surface to surface missiles.

At a given time, any celestial body is located directly over one point on the Earth's surface.

D0 denotes a critical diameter at which all molecules of a low dimensional glass are located on its surface.

Only the heat is extracted at the surface, and everything else that is brought up to the surface is re injected again, eliminating waste.

Land cover is the physical material at the surface of the earth.

It generally involves making marks on a surface by applying pressure from a tool, or moving a tool across a surface.

Fish of this family are commonly seen gulping at air at the surface of the water.

It is planned to have a network of at least four penetrators on the surface of an asteroid.

This occurs only at a specific angle and wavelength of incident light and is highly dependent on the surface of the gold, such that binding of a target analyte to a receptor on the gold surface produces a measurable signal.

The lake surface was at an altitude of 1,916 m above sea level.

At a surface elevation of , it is located along the border between California and Nevada, west of Carson City.

At a depth equal to half the wavelength λ, the orbital movement has decayed to less than 5 of its value at the surface.

This utilises a property of and other materials specifically that a thin layer of gold on a high refractive index glass surface can absorb laser light, producing electron waves (surface plasmons) on the gold surface.

Process When a sufficiently high voltage is applied to a liquid droplet, the body of the liquid becomes charged, and electrostatic repulsion counteracts the surface tension and the droplet is stretched at a critical point a stream of liquid erupts from the surface.

Single surface products. Furniture's a good one.

At the same time, something much more significant is happening beneath the economic surface.

For a solid shape such as a sphere, cone, or cylinder, the area of its boundary surface is called the surface area.

The energy of the laser heats the surface of the pellet into a plasma, which explodes off the surface.

And then for the damaged arthritis on the surface, we did a stem cell paste graft, which we designed in 1991, to regrow that articular cartilage surface and give it back a smooth surface there.

Because on Earth, almost all 99.9 percent of the methane is produced by living systems, not little green men, but microscopic life below the surface or at the surface.

Well, the surface of the spray coating is actually filled with nanoparticles that form a very rough and craggly surface.

How you grow legs out of a surface.

At this altitude, the air density is about 1 2200000 the density on the surface.

During the colder fall season, heat is lost at the surface and the epilimnion cools.

What Jonas did was not just go and do a surface look at the awful conditions that exist in such places.

(The two effects would cancel at a surface rock density of 4 3 times the average density of the whole earth.

If one integrates over a surface of uniform intensity I , for instance over a sphere centered around the point source, the equation becomes formula_2,where I is the intensity at the surface of the sphere, and r is the radius of the sphere.

As Jupiter has no surface, the base of its atmosphere is usually considered to be the point at which atmospheric pressure is equal to , or ten times surface pressure on Earth.

BC We separate from the lander going 125 miles an hour at roughly a kilometer above the surface of Mars 3,200 feet.

The often very high surface area to volume ratio of nanoparticles provides a tremendous driving force for diffusion, especially at elevated temperatures.

A surface such as a plane or the surface of a cylinder or sphere has a dimension of two because two coordinates are needed to specify a point on itfor example, both a latitude and longitude are required to locate a point on the surface of a sphere.

So, you pour them out onto a surface and they start to stick to that surface, and we take a picture using an atomic force microscope.

In 1804, Sir John Leslie observed that a matte black surface radiates heat more effectively than a polished surface, suggesting the importance of black body radiation.

So, they're all floating around in solution, and to look at them, you have to get them on a surface where they stick.

At the surface, the topographic expression is commonly an oceanic trench on the ocean side and a mountain range on the continental side.

In general, carbon block filters are more effective at removing a larger number of contaminants, based upon the increased surface area of carbon.

If a change in surface height represents an isostatically compensated change in crustal thickness, the rate of change of potential energy per unit surface area is proportional to the rate of increase of average surface height.

In the resulting battle, both sides lost numerous warships in two extremely destructive surface engagements at night.

The surface of Lake Malawi is located at above sea level, with a maximum depth of , which means the lake bottom is over below sea level at some points.
