A) less than V
B) more than V
C) equal to V
D) less than V for diatomic and more than V for monoatomic
Correct Answer: B
Solution :
When the pressure is first increased by \[10%\] it becomes (110/100) P. when it is decreased by \[10%\] from there, the pressure becomes \[\frac{110\times 90}{100\times 100}\,\,\,\,P\,\,=\,\,\frac{99}{100}\,P\] Thus the pressure decreases by \[1%\] volume is increased by nearly \[1%\]
