Answer:
DE = 170 [J]
Explanation:
The energy balance for a system that experiences any kind of process is expressed in a compact way as:
As energy can be transferred in the forms of heat, work, and mass, and its net transfer is equal to the difference between the amounts transferred in and out, the energy balance is expressed as it was showed before.
Now replacion the values in the given equation:
250 - 80 = DE
DE = 170 [J]
