Which of the following diagrams (figure) depicts ideal gas behaviour?A. B. C. D. |
|
Answer» We know that ideal gas equation is `pV =nRT` (a) When pressure p = constant From (i) volume `V prop` Temperature T (b) When T = constant From (i) pV = constant So, the graph is rectangular hyperbola. (C ) When V= Constant. From(i) `p prop T` So, the graph is straight line passes through the origin. (d) From (i) `p V prop T` `rArr " " (pV)/(T)=` constant `rArr` So, the graph hence through origin. So (d) is not correct. |
