What is the internal energy?
Rising temperature and changes in state or phase from solid to liquid and liquid to gas cause a rise in internal energy. Planetary bodies can be viewed as a fusion of heat engines and heat reservoirs
Internal drive U is the sum of the kinetic energy brought about by the motion of molecules and the potential energy brought about by the vibrational motion and electric energy of atoms. The energy contained in every chemical link is often referred to as internal energy. From a microscopic perspective, the internal energy can take on a variety of shapes. For any substance or chemical attraction between molecules.
Mol of decane = mass/ molar mass
= 1/142.29
1/142.29 mol gives internal energy =810.1 x58.8
So1 mol gives 810.1 x58.8x1/142.29 internal energy
so internal energy changes = 810.1 x58.8x1/142.29
