Properties and Measurable Quantities of Gases

• Gas

  • has no definite shape
  • temperature and pressure can be easily predicted
• Compressibility have huge intermolecular spaces. By exerting pressure, space can be diminished and particles bought closer. Compression implies a decrease in volume.
• Expansibility/Expandability is when pressure exerted, it contracts. When pressure freed, it expands. Intermolecular pull become less prominent, gas volume increases. Gas expands when heated and contracts when cooled.
• Diffusibility is the ability to spread out from higher concentration to lower concentration.
• Liquefaction - gases liquefy when sufficiently cooled.
• Low Density is that when gases have low density as companies with liquid and solid.
• Volume of gas is equal to volume of container because gas occupies all spaces available in its vessels.
• Pressure is the force exerted by the gas molecules on the walls of its container divided by the surface area of the container.
• Temperature is the average kinetic energy of the particles of a gas and usually determined using a thermometer.
