Answer:
The change in internal energy of the system = -772kJ
Explanation:
Given :
Heat lost by the system , a = -266KJ
Workdone by the system, W = -506KJ
The first law of thermodynamics states that:
Change in internal energy = q + w
Substituting values into the equation
Change in internal energy = (-266KJ) + (-506KJ)
Change in internal energy = -722KJ
