Answer:
- <u><em>Option D. qsys = - qsurr</em></u>
Explanation:
The symbol q is used to denote heat energy.
Considering positive the heat absorbed and negative the heat released:
- <em>qsys</em> is the heat absorbed by the systme
- <em>qsurr</em> is the heat absorbed by the surroundings
When the system does not do work on or receive work from the surroundings, the first law of thermodynamics states that:
- <em>qsys </em>+ <em>qsurr</em> = 0
From which:
- <em>qsys = - qsurr ← </em>answer
That is the option D.
That means that, the heat abosorbed by the system (if <em>qsys</em> is positive) equals the heat released by the surroundings, or the heat released by the system (if <em>qsys</em> is negative) equals the heat absorbed by the surroundings.
