Fast Compression: Increase in Pressure and Temperature

APPH12-MG4QNE

A physics instructor uses a “fire syringe” to demonstrate that energy is transferred to the molecules in a rapid compression. First the teacher places a very small square of tissue paper into a glass cylinder that is equipped with a moveable piston. Then the instructor slams down on the piston quickly compressing the gas around the tissue paper. Because the piston did so much work on the gas and increased the temperature so quickly, the tissue paper burned up in a tiny flame.

What is the name for the thermodynamic process described above?

A

isobaric

B

isothermal

C

isometric (isochoric)

D

adiabatic
