Answer:
- 300J
Explanation:
q= +600J
W= -900J
∆E = q+w
= 600-900
=-300J

Given :
Heat absorbed by the system (Q) = +600 J
Work done by the system (W) = 900 J
To Find :
The internal energy of the system (ΔE)
Solution :
According to First law of Thermodynamics,
Change in internal energy (ΔE) = Heat (Q) + Work Done (W)
In this question, work is done by the system and hence W = - 900 J
∴ Change in internal energy (ΔE) = Q + W
= 600 + (-900)
= -300 J
Therefore, the internal energy of the system is found to be -300 J.
