Answer:
Change in system's internal energy ΔU = 103 joules.
Adiabatic process as Q(heat exchange) = 0.
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.
Answer:
∆U = -103 joules
Process: adiabatic
Explanation:
Given: W = 103 J
Find: internal energy, ∆U; heat, Q
No heat transfer occurs, so Q = 0
∆U = Q – W
∆U = -W
∆U = -103 joules
Process: adiabatic
