What should be the percentage increase in pressure for a 5% decrease in volume of gas at constant temperature ?

Answer»

SOLUTION :Given, `P_(1)=P, V_(1)=V, T_(1)=T`,
`P_(2) =P_(2), V_(2)=V-(5V)/(100), T_(2)=T`
`P_(1)V_(1)=P_(2)V_(2)`
`rArr PV=P_(2) (V-(5V)/(100))`
`rArr P_(2) =(100)/(95) P=1.0526 P`
`THEREFORE" Increase in P "=0.0526 P`
`therefore %" increase in P "=0.0526xx100=5.26`
