MCQ
$Assertion :$ In adiabatic compression, the internal energy and temperature of the system get decreased.
$Reason :$ The adiabatic compression is a slow process.
  • A
    If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
  • B
    If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
  • C
    If the Assertion is correct but Reason is incorrect.
  • If both the Assertion and Reason are incorrect.

Answer

Correct option: D.
If both the Assertion and Reason are incorrect.
d
Adiabatic compression is a fast process. There is rise in temperature and also increase in internal energy. So, both are false.
