Describing Gases

• Fundamental properties of Gas. The three states of matter differ in properties. One of the basic distinctions in their differences is the arrangement of their particles.
• there are 11 known gaseous elements which include the diatomic molecules, hydrogen, nitrogen, oxygen, fluorine , and chlorine , and the noble gases helium, neon, argon, krypton, xenon And radon
• Gases hare important fundamental properties that are measurable such as volume, pressure, temperature, and amount of the gas or number of moles.
• Volume- Molecules of gases occur space. It may be proven when the gas pills up its container.
• when you inflate a

  balloon it expands

  because molecules of gases strike the walls of the balloon

  causing pressure on it- The pressure of tie gas is the force exerted by the gas per unit area.
• Temperature- Gas expands due to an increase in temperature: This temperature is dependent on the kinetic energy of the gas
• Amount of gas- the mass of the gas is related to the number of moles of the gas.
• An Anglo-Irish Chemist- Robert Boyle
• the product of pressure and volume is constant, thus, it is written as follows: p1 v1=p2 v2
• French physicist named Jacques Alexandre Charles performed an experiment in a balloon,
• Fron his experiments, Charles has shown us that as the volume increases or decreases the temperature manifest the same increase or decrease, which pertain to a direct relationship .
• Kelvin = 273.15
