Pressure And General Gas Law (Boyle’s Law And Charles’s Law)

Pressure And General Gas Law (Boyle's Law And Charles's Law)
  • Boyle’s Law
  • Charles’ Law
  • Pressure Law
  • General gas Law

In the attempt to understand the behaviour of gases in relation to temperature, volume and pressure. The following variables are examined.

  • variations in volume due to the pressure and temperature Boyle’s law
  • Variation of volume in relation to the temperature, pressure and temperature.
    Charles law
  • Variation in pressure with temperature at the same volume Pressure law

Boyle’s Law

Boyle’s law says that the pressure of a certain mass of gas changes inversely with the volume temperature.

 

Charles’ Law

Charles law stipulates that for a fixed gas mass that is pressure constant, its quantity is proportional to the temperature at which it is absolute

 

Pressure Law

The law of pressure states that pressure for a certain gas mass at a an unvarying volume is proportional temperature absolute.

 

Absolute Zero of Temperature

In the event that the volumes of pressure, temperature or pressure-temperature are extrapolated backwards, they cut the temperature axis around -273 zeroC. This temperature is referred to as absolute zero. It is the point at where the volume of gas is thought to be zero as it is cooling. At that temperature, the gas molecules stop moving completely. The temperature of this is an presumption, since gas molecules are known to melt most of the time prior to the temperature being attained.

General gas Law

The gas law generalized is the result of the Boyle’s law, Charles Law, and Pressure Law.
