50) the volume of a gas with a pressure of 1.2 atm increases from 1.0 l to 4.0 l. what is the final pressure of the gas, assuming constant temperature and amount of gas? 50)

Sagot :

Final pressure of the gas assuming constant temperature and amount of gas is 0.30 atm.

Final pressure of the gas can be calculated from the expression pf Boyle's law. Boyle's law states that when temperature and mass is kept constant, the volume of a gas varies inversely with pressure. The equation for this law is

          P1 V1 = P2 V2.

here  the volume of a gas with a pressure of 1.2 atm. increases from 1.0 l to 4.0 l. so,

      P1 = 1.2 atm. V1=1.0 and  L2 = 4.0 L

Rearranging the expression we get the value,

   P2=P1V1 / V2

   P2=(1.2atm×1.0L) / 4.0 L

        = 0.30 atm.
