To find the change in the internal energy of a system, which equation would you use?

The answer is ΔU = Q -W

Explanation:

The internal energy is the result of the contribution of the kinetic energy of the molecules or atoms that constitute it, of their rotation, translation and vibration energies, in addition to the intermolecular potential energy due to gravitational, electromagnetic and nuclear forces.

Internal energy is a function of the thermodynamic variables that are necessary to define the state of the system.

To find the internal energy change, the equation ΔU = Q -W is used.

i think this picture will you.
