Misalan tambayoyi kan amfani da dokar farko ta thermodynamics ga hanyoyin thermodynamic daban-daban (isobaric, isothermal, isochoric)

11 Misalan tambayoyi kan amfani da dokar farko ta thermodynamics ga hanyoyin thermodynamic daban-daban (isobaric, isothermal, isochoric)

1. Jadawalin da ke ƙasa yana nuna zagayowar thermodynamic da gas ke fuskanta. Aikin da iskar gas ke yi a cikin tsarin ABCD shine…

Misalan tambayoyi kan amfani da dokar farko ta thermodynamics ga hanyoyin thermodynamic daban-daban (isobaric, isothermal, isochoric) - 1Tattaunawa
An sani :
Matsi na 1 (P)1= 2 x 105 Pa
Matsi na 2 (P)2= 4 x 105 Pa
Juzu'i na 1 (V)1= 1m3
Juzu'i na 2 (V)2= 3m3
An tambaya Aikin da iskar gas ta yi a cikin tsarin zagayowar ABCD
Jawab :
Aikin da ake yi da iskar gas = yankin murabba'i mai siffar murabba'i ABCD.
W = (P)2 - P1)(V2 - V1)
W = (4 x 105 - 2 x 105)(3 – 1)
W = (2 x 105(2)
W = 4 x 105 Joule
Aikin da iskar gas ke yi a cikin tsarin zagayowar ABCD shine 4 x 105 Joule.

An gama aikin = yankin da ke ƙarƙashin lanƙwasa AB = yankin alwatika + yankin murabba'i mai kusurwa huɗu
W = [½ (8 x 10)5–4 x 105)(3-1)] + [4 x 105 (3-1)]
W = [½ (4 x 10)5)(2)] + [4 x 105 (2)
