Experimental Objectives

  • To establish the relationship between the volume and pressure of a confined gas
  • To determine mathematical relationship between gas pressure and volume of a gas in a confined system
  • To use established mathematical relationship to determine pressure or volume gas when of one of the variable is changes at constant temperature

Theory

According to Fowler, Boyles Law states that at constant temperature, the pressure of a given gas is inversely proportional to the volume (1).Boyle discovered that when pressure of a gas is increased by two-fold, the volume of a gas will contract to half its earlier volume at constant temperature. A plot of pressure against volume of an ideal gas at constant temperature gives a negative inclined graph curve, an indication of inverse proportionality. Therefore, in mathematical terms, the relationship can be expressed as,

PV=Constant or PV=k &&.. (1)

Where P=pressure of gas, V=volume of gas and k=a constant of proportionality of ideal gas

Boyles Law is utilized in calculating changes in pressure and volume at steady temperatures (initial and final pressure and volume). This is calculated using the equation: p1V1=p2V2& (2)

Where: p1=initial pressue, V1=initial volume, p2=final pressure and V2=final volume
