A sample of helium gas with an initial temperature of Ti in an insulated cylinder with initial volume Vi is suddenly and violently compressed to one-half its volume. The absolute temperature of the gas after the compression is observed to have doubled. (Note: In a quasistatic adiabatic compression of a monatomic gas, TV2/3= constant.) A suitable replacement process for this process would be
A. a slow isothermal compression from Vi to 
Vi.
B. a slow adiabatic compression from Vi to Vi.
C. Heating the gas to double its temperature followed by a slow adiabatic compression from Vi to Vi.
D. a slow adiabatic compression from Vi to Vi followed by heating to bring the temperature to 2Ti.
E. a slow adiabatic compression from Vi to Vi followed by cooling to bring the temperature to 2Ti.
F. None of the above.
