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:

P1V1T1=P2V2T2

where:
P1=P2 (pressure remains constant)
V1=2.2L
T1=37+273=310K
T2=8.6+273=281.6K

2.2×310281.6=V2

V2=2.4L

Therefore, the expelled air would occupy 2.4 L at 8.6 °C.
