The relations between various variables of gaseous substances are given along with their formulae .

Options

A. Density and molar mass : `M = (dRT)/(P)`
B. Universal gas constant , P , V , T : `R = (PV)/(nT)`
C. Volume and pressure : `V_(2) = (P_(2)V_(1))/(P_(1))`
D. Volume and temperature : `V_(2)= (V_(1) T_(2))/(T_(1))`

Answer

C

Explanation

`P_(1)V_(1)=P_(2)V_(2)` hence, `V_(2)=(P_(1)V_(1))/(P_(2))`
