WebIn all chemical reactions the energy can be gained or lost. The 1st Law of Thermodynamics can be illustrated by the equation: ΔU=W+Q. INTERNAL ENERGY is the total energy of the system – the sum of all kinetic energies of all particles (e. vibrational, transitional, chemical, rotational etc.) and their potential energy. It cannot be measured. WebDemonstração: U= (3/2)PV ou U= (3/2)nRT. Trabalho feito por processo isotérmico. Ciclo de Carnot e máquina de Carnot.
