Its answer is wrong .its isotheromic
Sir its wrong. Isothermal… Is correct
Es k ans to isothemal ay ga
The correct ans is b . According to Newton sound travel in air under isothermal condition. Plz correct the answer .
Newton calculated speed of sound in air under the isothermal condition which was 281m/s this value was 16% less than experimental value then it was corrected by Laplace .he calculated speed of sound under the adiabatic condition. Plz the correct answer is b ( isothermal) please the correct the option. And request that please upload mcqs from books. This mcqs is copy from geek mcqs where this answer is incorrect.
Newton deals with constant temp means isothermal process
Sir according to newton sound travel by isothermal process not by isobaric……
Correct ans is isothermal.
Not isobaric.
Network assume propagation of sound in air is isothermal process.
Answer is isothermal
The correct answer is option’ b ‘ the isothermal process becuase his calculations was then corrected by Laplace by considering adiabatic process during sound propogation.
Isothermal is correct ans
B is the right answer
The answer is thermal, which is option B. By this mistake he gets velocity of sound 280 m per second which is 16% less than the experimental value at zero degrees centigrade (332 meters per second). This mistake was corrected by Laplace.
Here B is the right answer. Newton said that sound waves passing through a medium do not change the temperature during rarefaction and compression and it is isothermal process. Laplace corrected this and said the law applied here is the Boyles Law for adiabetics.
Speed of sound depends upon pressure so isobaric is corect
It’s isothermal
