The air temperature over a lake decreases linearly with height after sunset, since air cools faster than water. The mean molar mass of air is M=28.8×10−3kg/mol. If the temperature at the surface is 28.00 ∘C and the temperature at a height of 300.0 m is 8.000 ∘C how long does it take sound to rise 300.0 m directly upward? [Hint: Use the equation v=√γRT/M and integrate. At a height of 300.0 m, how far does sound travel horizontally in this same time interval?
There is a problem in the solution.first change temperature from celcious to kelvin then put them in equation(1).rest the process is correct.
Still,If you face any prblm going through the solution,let me know by commenting.
