A) \[33.3\]
B) \[50.0\]
C) \[100.0\]
D) \[300.0\]
Correct Answer: D
Solution :
Key Idea: In an isothermal change temperature remains constant. For isothermal change \[PV=RT=\]constant where, \[P=h\rho g=\]height\[\times \]density\[\times \]gravity \[\therefore \] \[{{P}_{1}}{{V}_{1}}={{P}_{2}}{{V}_{2}}\] Given,\[{{V}_{2}}=3{{V}_{1}},\,\,{{P}_{2}}=1000\,\,kPa=100\times {{10}^{3}}Pa\] \[\therefore \]\[{{P}_{1}}=\frac{{{P}_{2}}{{V}_{2}}}{{{V}_{1}}}=\frac{100\times {{10}^{3}}\times 3{{V}_{1}}}{{{V}_{1}}}=300\,\,kPa\]You need to login to perform this action.
