A sound wave passing through an ideal gas at NTP produces a pressure change of 0.001 dyne / cm ^2 during adiabatic compression. The corresponding change in temperature ( =1.5 for the gas and atmospheric pressure is 1.013 10^6 dyne / cm ^2 ) is
Options
- A8.97 10⁻⁴ ~K
- B8.97 10⁻⁶ ~K
- C8.97 10⁻⁸ ~K
- D8.97 10⁻⁹ ~K
Correct answer
C. 8.97 10⁻⁸ ~K
Step-by-step solution
T^ p^ 1- = constant or T^ =p^ -1 aligned T & =p ( -1 ) T T & = -1 p p T T & = ( 1.5-1 1.5 ) 0.001 1.013 10^6 T & =8.98 10⁻⁸ ~K aligned
