Blowing Air with open pipe is an example of :
-
- Isothermal process
- Isochroric process
- Isobaric process
- Adiabatic process
- Isothermal process
Correct Option: C
When air is suddenly exhaled out into a larger volume through the narrow opening, air undergo adiabatic expansion. So blowing air is an adiabatic process. But since it is open pipe, the pressure inside and pressure outside remains same. So ultimately the process is isobaric.
