Q. Blowing air with open mouth is an example of
A) Isobaric process
B) Isochoric process
C) Isothermal process
D) Adiabatic process
Explanation
(a) We know that blowing air (if sudden) is an adiabatic process. But it is not given as sudden process. Also, as the mouth is open, pressure inside and outside is same. Thus, blowing air with open mouth is isobaric process.
