Answer:
Change in system's internal energy ΔU = 103 joules.
Adiabatic process as Q(heat exchange) = 0.
Step-by-step explanation:
From, first law of thermodynamics,
Heat energy given to system = change in internal energy + work done by system
⇒ Q = ΔU + W.
here, given that heat exchange is negligible,⇒ Q =0 .
work is done on the system, ⇒W = -103 joules
⇒ ΔU = Q - W = 0 -(-103) = 103 Joules.
This process, where there is no heat exchange is adiabatic process.
