identify the correct relation.

δe system = -δe surroundings

δe system = δe surroundings

δe system = -δe universe

δe system = δe universe

Explanation:

According to the law of conservation of energy, the total energy of the universe is constant. So, the change in energy of the system ($\Delta E_{\text{system}}$) and the change in energy of the surroundings ($\Delta E_{\text{surroundings}}$) must add up to zero. Mathematically, $\Delta E_{\text{system}}+\Delta E_{\text{surroundings}} = 0$, which can be rewritten as $\Delta E_{\text{system}}=-\Delta E_{\text{surroundings}}$.

Answer:

$\Delta E_{\text{system}} = -\Delta E_{\text{surroundings}}$
