Gases can be compressed easily because there is a large amount of space between the individual molecules, which are very active and move around at high speed. When gas is compressed, the particles are forced much closer together, allowing a huge amount of particles to fit in a small space.Continue Reading
One common use of compressed gas is in scuba diving tanks, where oxygen is compressed to the point that 600 liters can fit into a three liter tank. As gas particles move so rapidly, they seek areas of less concentration to give them more area to move around. This leads to compressed gas rapidly escaping a container if it is not properly sealed.
Of the three basic states of matter, the particles in gas are much further apart than in liquid or solid matter. Some liquids can be slightly compressed, while most solids cannot be compressed at all, except for a small group that includes synthetic and natural rubbers. In addition to solids, liquids and gases, scientists have also discovered two other forms of matter: plasma and Bose-Einstein condensate. Plasma occurs naturally in lightning and is made in laboratories to be used in televisions and other electronics. Bose-Einstein condensate was discovered in 1995 and can only be made in a lab under extremely cold temperatures.Learn more about States of Matter
There is no air in space because there is no gravity to condense the molecules of gases found there into air. On Earth, gravity holds nitrogen, oxygen and the other gases that compose the atmosphere together, but only to about 60 miles above the surface.Full Answer >
Examples of gases include oxygen, nitrogen, helium, hydrogen, argon, fluorine, krypton, neon, radon, xenon and chlorine. These gases are single elements, though many gases are compounds or mixtures. Such gases include carbon dioxide, carbon monoxide, methane, air, ammonia, formaldehyde, ozone, nitrous oxide and natural gas.Full Answer >
Fire is primarily composed of several gases ignited by a source of heat and exposure to oxygen. Visible flames are the result of the energy given off through a chemical reaction caused by the burning of a fuel source.Full Answer >
Sublimation is the scientific process in which solids are changed to gases without passing through the liquid phase. Sublimation occurs when temperatures and pressures are below the triple point. The triple point is the temperature and pressure at which substances can coexist in solid, liquid and vapor forms.Full Answer >
