Question

At 0°C and 760 mm Hg pressure, a gas occupies a volume of 100 cm3. The Kelvin temperature (Absolute
temperature) of the gas is increased by one-fifth while the pressure is increased one and a half times.
Calculate the final volume of the gas.​

Answer 1

Answer:47.9

Explanation:combining boyle's law and charle's law ,

we have , p1v1/t1=p2v2/t2                              p1=760mm=76cm of hg

              = 76*100/273=190*v2/327.6             v1=100cm3

=     27.8*327.6/190                                         t1=0degree celsius=273K

= 9120*190

=  48cm3

                                                                         p2=76+3/2*76=190mm of hg

              (ans.)                                                  v2=?

                                                                         t2=273+1/5*273=327.6K
