Estabelecimento do Conceito de Temperatura como uma grandeza derivada da Energia e da Entropia
Rodrigo de Abreu
Temperature is introduced as a derived concept from energy and entropy. We consider two sub-systems in equilibrium for several configurations. The equality of temperature of the su…
Analise Termodinamica da aceleracao de uma massa
Rodrigo de Abreu
We analyse the acceleration of a mass with a simple structure taking into account Thermodynamics. Two situations are analysed. The first one for the application of a localized forc…
Analise Termodinamica de um circuito RLC
Rodrigo de Abreu
We analyse a RLC circuit taking the Second Law of Thermodynamics into consideration.
A Segunda Lei da Termodinamica na formulacao da Lei de Hooke
Rodrigo de Abreu
Hooke's Law is analyzed taking the Second Law of Thermodynamics into consideration. It is shown that the energy of a spring isn't always 1/2 k xx - this value is actually the energ…
Analise dinamica da tendencia para o equilibrio num modelo simples: a Segunda Lei de Newton e a Segunda Lei da Termodinamica
Rodrigo de Abreu
We relate Newton's Second Law with the Second Law of Thermodynamics through the analysis of a simple model introducing a dynamic pressure concept. From this analyses we can clarify…
