Question
After the adiabatic expansion described in the previous part, the system undergoes a compression that brings it back to its original state. Which of the following statements is/are true? Check all that apply.
The total change in internal energy of the system after the entire process of expansion and compression must be zero.
The total change in internal energy of the system after the entire process of expansion and compression must be negative.
The total change in temperature of the system after the entire process of expansion and compression must be positive.
The total work done by the system must equal the amount of heat exchanged during the entire process of expansion and compression.
Many thank for answering
Explanation / Answer
The total change in internal energy of the system after the entire process of expansion and compression must be zero. ( true )
final and initial states are same means the temperature is same so chnge in internal energy is zero
The total change in internal energy of the system after the entire process of expansion and compression must be negative ( false )
The total change in temperature of the system after the entire process of expansion and compression must be positive ( false )
The total work done by the system must equal the amount of heat exchanged during the entire process of expansion and compression ( true )
