You want to design a breathing machine that will bring 500 ml of sue into the lungs. You begin with 100 ML of air at 2 atm of pr
olasank [31]

The pressure of the machine has to be reduced to 0.4 atm in order for the breathing machine to bring 500 ml of air into the lungs.

<h3>What is the relationship between volume and pressure?</h3>

Volume and pressure are inversely relate as given by the Boyle's law equation below:

  • P_{1}V_{1} = P_{2}V_{2}

The complete question is as follows:

<em>You Want To Design A Breathing Machine That Will Bring 500 ML Of Air Into The Lungs. You Begin With 100 ML Of Air At 2 atm Of Pressure. How Would You Change The Pressure In Your Machine To Accomplish Your Goal?</em>

From the question, P_{1} = 2\:atm, V_{1} = 100\:mL, P_{2}=?, V_{2} = 500\:mL

The change in pressure, P_{2} will be:

P_{2} = \frac{P_{1}V_{1}}{V_{2}}\\ P_{2} =\frac{100\times2}{500}=0.4\:atm

Therefore, the pressure of the machine has to be reduced to 0.4 atm in order for the breathing machine to bring 500 ml of air into the lungs.
