the work done by the system during a certain adiabatic process is 200J. What is the change in U of the system
To determine the change in internal energy (ΔU) of the system, you need to know the work done (W) and the heat transfer (Q) during the process. However, the given information only specifies the work done (W).
In an adiabatic process, no heat is exchanged between the system and its surroundings (Q = 0). Therefore, the change in internal energy (ΔU) can be calculated using the first law of thermodynamics:
ΔU = Q - W
Since Q = 0 for an adiabatic process, the equation simplifies to:
ΔU = 0 - W
Substituting the value for work (W) as 200 J, the equation becomes:
ΔU = 0 - 200 J
Thus, the change in internal energy (ΔU) of the system during this adiabatic process is -200 J.
