A volume of 2.2 L of air at 37. °C is expelled from the lungs into cold surroundings at 8.6 °C. The pressure and the number of gas particles do not change.
What volume (in L) does the expelled air occupy at 8.6 °C? Be sure your answer has the correct number of significant figures.
1 answer
Using the ideal gas law equation:
where: (pressure remains constant)
Therefore, the expelled air would occupy 2.4 L at 8.6 °C.
