    Malengo ya kujifunza

    Mwishoni mwa sehemu hii, utaweza:

    • Eleza taratibu za kurekebishwa na zisizoweza
    • Weka sheria ya pili ya thermodynamics kupitia mchakato usioweza kurekebishwa

    Fikiria gesi bora ambayo inafanyika katika nusu ya chombo cha maboksi ya joto na ukuta katikati ya chombo. Nusu nyingine ya chombo iko chini ya utupu bila molekuli ndani. Sasa, kama sisi kuondoa ukuta katikati haraka, gesi expands na kujaza chombo nzima mara moja, kama inavyoonekana katika Kielelezo\(\PageIndex{1}\).

    Sehemu ya a ya takwimu inaonyesha chombo ambacho kina gesi katika nusu ya kushoto na utupu katika nusu sahihi. Sehemu ya b inaonyesha chombo ambacho kinajazwa kabisa na gesi.
