Processo Isoc\u00f3rico – Processo Isom\u00e9trico<\/span><\/h2>\n

Um\u00a0<\/span>processo isoc\u00f3rico<\/span><\/strong>\u00a0\u00e9 um processo termodin\u00e2mico, no qual o\u00a0<\/span>volume<\/span><\/strong>\u00a0do sistema fechado\u00a0<\/span>permanece constante<\/span><\/strong>\u00a0(V = const).\u00a0Ele descreve o comportamento do g\u00e1s dentro do recipiente, que n\u00e3o pode ser deformado.\u00a0Como o volume permanece constante, a transfer\u00eancia de calor para dentro ou para fora do sistema n\u00e3o\u00a0<\/span>funciona<\/span><\/a>\u00a0, mas altera apenas a\u00a0<\/span>energia interna<\/span><\/strong><\/a>\u00a0(a temperatura) do sistema.<\/span><\/p>\n

Na engenharia de\u00a0<\/span>motores de combust\u00e3o interna<\/span><\/strong>\u00a0, os processos isoc\u00f3ricos s\u00e3o muito importantes para seus ciclos termodin\u00e2micos (ciclo Otto e Diesel), portanto, o estudo desse processo \u00e9 crucial para a engenharia automotiva.<\/span><\/p>\n
