Answer: The work done by the system is 800 Joules.
Explanation:
Internal change in thermal energy of the system,[tex]\Delta U[/tex]= 600 Joules
Energy added to the system the system,Q = 1400 Joules
Work done by the system can be calculated by using First law of thermodynamics:'
[tex]\Delta U=Q-W[/tex] (First law of thermodynamics)
[tex]600 J=1400 J-W[/tex]
[tex]W=Q-\Delta U=1400 J-600 J=800 J[/tex]
The work done by the system is 800 Joules.
