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.Know More
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 >
The five phase changes of matter are solids, liquids, gases, plasmas and Bose-Einstein condensates. Elements are able to move between these phases when certain physical conditions exist.Full Answer >
Ideal gases are hypothetical substances studied by scientists and students to simplify intermolecular forces. Ideal gases are point masses that constantly move in a random, straight-line nature. The behavior of ideal gases, meaning the relationship of pressure (P), temperature (T) and volume (V) is summarized as PV=nRT, where "n" is the number of moles of gas. This equation for ideal gases will always equal one.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 >
