A vessel of volume \(V\) contains ideal gas having mass density \(\rho\) at temperature \(T\) and pressure \(p\). After a portion of the gas is let out, the pressure in the vessel is decreased by \(\Delta p\). The mass of the released gas is
- A \(\rho V \Delta p / p\)
- B \(\frac{\Delta p}{p}\)
- C \(\frac{\rho}{p}\)
- D \((\rho V)^2 \Delta p / p\)
Answer & Solution
Correct Answer
(A) \(\rho V \Delta p / p\)
Step-by-step Solution
Detailed explanation
Given, initial value of volume, pressure and temperature of an ideal gas in vessel, \[ V_1=V, p_1=p \text { and } T_1=T \] and density of gas \(=\rho\) When, \(\Delta V\) volume of gas is let out, hence pressure of gas is decreased to \(\Delta p\). Then,…
