At constant temperature, increasing the pressure of a gas by 5 % its volume will decrease by
Options
- A5 %
- B5.26 %
- C4.20 %
- D4.70 %
Correct answer
D. 4.70 %
Step-by-step solution
According to ideal gas law at constant temperature, P 1 ~V array ll & P ₁ ~V ₁= P ₂ ~V ₂ & P ₁= P & P ₂= P + 5 100 P =1.05 P array Substituting the values array ll & PV ₁=1.05 PV ₂ & V ₂ ~V ₁ = 1 1.05 & V ₂- V ₁ ~V ₁ 100= 1-1.05 1.05 100 & V V ₁ =-4.76 % -4.7 % array The negative sign indicates that the volume is decreasing.
