Konceptet themelore n\u00eb termodinamik\u00eb<\/h2>\n\n

Ekuacioni i procesit adiabatik<\/strong> <\/h3>\n\n

Ekuacioni adiabatik<\/strong> rrjedh nga ligjet e termodinamik\u00ebs dhe vetit\u00eb specifike t\u00eb gazeve ideale. Ja si merret: <\/p>\n\n

1. Parimi i par\u00eb i termodinamik\u00ebs i zbatuar n\u00eb sistemin adiabatik<\/strong><\/h4>\n\n

Parimi i par\u00eb i termodinamik\u00ebs shkruhet: U=QW<\/em> me, U energjin\u00eb e brendshme t\u00eb sistemit termodinamik, Q nxeht\u00ebsin\u00eb e shk\u00ebmbyer nd\u00ebrmjet sistemit dhe mjedisit t\u00eb tij dhe W pun\u00ebn mekanike q\u00eb kryen sistemi n\u00eb mjedisin e tij ose anasjelltas.<\/p>\n\n

N\u00eb rastin e nj\u00eb procesi adiabatik<\/strong> , nuk ka transferim t\u00eb nxeht\u00ebsis\u00eb (Q=0): U= -W<\/em><\/p>\n\n

2. Sistem ideal gazi dhe adiabatik<\/strong><\/h4>\n\n

Puna W e kryer nga nj\u00eb gaz ideal gjat\u00eb zgjerimit ose ngjeshjes s\u00eb tij jepet nga:<\/p>\n\n

W = P dV<\/em><\/p>\n\n

Duke p\u00ebrdorur ekuacionin ideal t\u00eb gjendjes s\u00eb gazit (PV= nRT), kjo na lejon t\u00eb z\u00ebvend\u00ebsojm\u00eb P me P= nRTV<\/em><\/p>\n\n

Duke p\u00ebrdorur relacionin = CpCv dhe R = Cp-Cvon mund t\u00eb shprehim RCv= -1<\/em> . <\/p>\n\n

Ne marrim, TV-1 = konstante<\/em><\/p>\n\n

4. Ekuacioni i transformimit adiabatik<\/strong><\/h4>\n\n

Duke p\u00ebrdorur ekuacionin ideal t\u00eb gjendjes s\u00eb gazit dhe duke z\u00ebvend\u00ebsuar T, marrim ekuacionin themelor t\u00eb nj\u00eb sistemi adiabatik<\/strong> : PV = konstante<\/p>\n\n
