a system uses 2,380 j of energy to do work as 12,900 j of heat are added to the system. the change in internal energy of the system is j.

a system uses 2,380 j of energy to do work as 12,900 j of heat are added to the system. the change in internal energy of the system is j.

Answer

Explanation:

Step1: Recall the first - law of thermodynamics

The first - law of thermodynamics is given by $\Delta U = Q - W$, where $\Delta U$ is the change in internal energy, $Q$ is the heat added to the system, and $W$ is the work done by the system.

Step2: Identify the values of $Q$ and $W$

We are given that $Q = 12900\ J$ (heat added to the system) and $W=2380\ J$ (work done by the system).

Step3: Calculate the change in internal energy

Substitute the values into the formula: $\Delta U=Q - W=12900 - 2380$. $\Delta U = 10520\ J$.

Answer:

$10520$
