[mwit1967]

Two identical samples of a monatomic gas are initially at pressure P and occupy volume V. You perform two experiments which will both lead to the gas samples being compressed to final volumes one-third as large as their initial volumes.
 
  In one of the experiments you make the gas undergo an isothermal compression. In the second you make the gas undergo an adiabatic compression. It is correct to say that: A) The isothermal compression leads to a higher final pressure than the adiabatic compression and the gas exchanges heat with its surroundings.
  B) The adiabatic compression leads to a higher final pressure than the isothermal compression and the gas does not exchange heat with its surroundings.
  C) The isothermal compression leads to a lower final pressure than the isothermal compression and the gas does not exchange heat with its surroundings.
  D) The adiabatic compression leads to a lower final pressure than the isothermal compression and the gas exchanges heat with its surroundings.
  E) It is impossible to predict on the basis of this data.
