Question

A sample of gas occupies 10.0 l at 100.0 torr and 27.0
c. calculate the pressure if the temperature is changed to 127c while the volume remains constant. (133 torr)

1 Answer

  • The pressure  of a sample  of a gas if the temperature  is changed  to 127  c  while  the volume  remains  constant   is calculated  using gay lussac law formula

    that is P1/T1 = P2/V2
    P1 = 100 torr
    T1 = 27+273 = 300 k
    T2 =127 +273 =400 k
    P2=?

    by  making P2 the subject of the formula
    P2=T2P1/T1

    =100  x 400/300 = 133.3 torr
