Question

what is effect of change of pressure on gases

Answer 1

When pressure increases, the volume of the gases decreases. When pressure decreases, the volume of the gases increases.

Answer 2

By the use of Boyle's law we can explain effect of pressure on real gases. {see attached}.

*Acc. to graphical representation, following results were obtained:-)

1) At low pressure, value of Z nearly one four real gases i. e. they behave as ideal gas.

2) lf Z>1 then positive deviation takes place which means gases are compressible comma because their molecular mass is less ( H2 and He) .

3)lf Z<1 then negative deviation takes place which means gases are compressible because their molecular mass is more (CO and CH4) .
