Physics Question on Kinetic molecular theory of gases
In a process, the work done by the system is equal to the decrease in its internal energy. The process that the system undergoes is:
A
isothermal process
B
adiabatic process
C
isobaric process
D
isochoric process
Answer
adiabatic process
Explanation
Solution
The correct option is: (B): adiabatic process.
In line with the first law of thermodynamics, the equation states that:
dQ = dU + dW
Given that dW = -dU, it follows that:
dQ = 0
As a result, the heat transfer within the system equals zero. Consequently, this implies the process could be adiabatic.
