what is meant by the internal energy of a system？
Internal energy U of a system or a body with well defined boundaries is the total of the kinetic energy due to the motion of molecules and the potential energy associated with the vibrational motion and electric energy of atoms within molecules. Internal energy also includes the energy in all the chemical bonds.

What do you mean by internal energy of a gas?
The internal energy of an ideal gas is therefore the sum of the kinetic energies of the particles in the gas. The kinetic molecular theory assumes that the temperature of a gas is directly proportional to the average kinetic energy of its particles, as shown in the figure below.Energy, Enthalpy, and the First Law of Thermodynamics - Purdue Universityhttps://chemed.chem.purdue.edu › topicreview › chemicalhttps://chemed.chem.purdue.edu › topicreview › chemical
