Place a small amount of cotton or a
match head in the tube. Dim
the room lights. Quickly force the plunger down. This
rapidly compressed air should heat up enough to ignite the match head.
NOTES
Tf = To
(Vo/Vf)(γ-1).
The volume typically decreases by a factor
of about 20.
For nitrogen and oxygen, cp/cv
= 1.4.
To=300 K.
Tf = 300*(20)0.4 = 994 K.
