Question

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 true and reason is the correct explanation of assertion
B. If the assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false

Answer 1

Correct Answer - D
When a process takes place very rapidly so that the heat does not find time to flow in or out then the process is adiabatic. Adiabatic compression is a rapid action and both the internal energy and the temperature increase.
