Entropia no Absoluto Zero<\/h2>\n

De acordo com a terceira lei da termodin\u00e2mica:<\/strong><\/p>\n

A entropia de um sistema se aproxima de um valor constante \u00e0 medida que a temperatura se aproxima do zero absoluto.<\/em><\/p>\n

Com base em evid\u00eancias emp\u00edricas, esta lei afirma que a\u00a0entropia de uma subst\u00e2ncia cristalina pura \u00e9 zero<\/strong>\u00a0no\u00a0zero\u00a0<\/strong>absoluto de temperatura<\/strong>\u00a0, 0 K e que \u00e9 imposs\u00edvel por meio de qualquer processo, n\u00e3o importa o ideal, reduzir a temperatura de um sistema para zero absoluto em um n\u00famero finito de etapas.\u00a0Isso nos permite definir um ponto zero para a energia t\u00e9rmica de um corpo.<\/p>\n

O zero absoluto \u00e9 a temperatura te\u00f3rica mais fria, na qual o movimento t\u00e9rmico de \u00e1tomos e mol\u00e9culas atinge seu m\u00ednimo.\u00a0Este \u00e9 um estado no qual a entalpia e a entropia de um g\u00e1s ideal resfriado atingem seu valor m\u00ednimo, tomado como 0.\u00a0Classicamente<\/strong>\u00a0, esse seria um estado de\u00a0imobilidade<\/strong>\u00a0, mas\u00a0a<\/strong>\u00a0incerteza\u00a0qu\u00e2ntica<\/strong>\u00a0determina que as part\u00edculas ainda possuem uma\u00a0energia finita de ponto zero<\/strong>\u00a0.\u00a0O zero absoluto<\/strong>\u00a0\u00e9 indicado como 0 K na escala Kelvin,\u00a0-273,15 \u00b0 C<\/strong>\u00a0na escala Celsius e\u00a0-459,67 \u00b0 F<\/strong>\u00a0na escala Fahrenheit.<\/p>\n<\/div>\n<\/div>\n
