Q147 / 180 · COMEDK 2019 · Physics

Blowing air with open mouth is an example of

  • A
    isothermal process
  • B
    adiabatic process
  • Correct answer
    C
    isobaric process
  • D
    isochoric process

Solution

The pressure inside our body is usually equal to the atomospheric pressure. Since, our mouth is open when blowing air, it will have the same pressure as the atmosphere, Hence, blowing air with open mouth is an example of isobaric process.

Hence, the correct answer is option: 'C'.
