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

Hey Thermodynamics is defined as the branch of science that deals with the relationship between heat and other forms of energy, such as work. It is frequently summarized as three laws that describe restrictions on how different forms of energy can be interconverted. Chemical thermodynamics is the portion of thermodynamics that pertains to chemical reactions.

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.
