A) \[1kg\]
B) \[2kg\]
C) \[3kg\]
D) \[4kg\]
Correct Answer: C
Solution :
According to question, temperature and volume are constant, hence from ideal gas equation, we have \[\frac{{{P}_{1}}}{{{P}_{2}}}=\frac{{{n}_{1}}}{{{n}_{2}}}\] or \[\frac{{{P}_{1}}}{{{P}_{2}}}=\frac{{{\omega }_{1}}}{{{\omega }_{2}}}\] \[\therefore \] \[\frac{10}{8}=\frac{15}{{{\omega }_{2}}}\] \[{{\omega }_{2}}=12kg\] Hence, gas leaked \[=15-12=3kg\]
