kak jawab kak yg bnr ya kak jwbnya



jawab pake cara ya kak​

Answer 1

Jawaban:

Penjelasan:

2)  

T₁ = 30°C = 303 °K

V₁ = 2 m³

T₂ = 80°C = 353 °K

P = 2.10⁵ N/m²

Usaha = ?

Proses Isobarik

V₁/T₁ = V₂/T₂

V₂ = V₁/T₁ . T₂

V₂ = 2/303 . 353

V₂ = 2,33 m³

Usaha

W = P. ΔV

W = 2.10⁵.(2,33-2) = 0,66.10⁵ J

3)

V₁ = 2,5 m³

V₂ = 6,5 m³

P = 3 atm = 3,03.10⁵ Pa

Usaha luar gas ?

W = P.( V₂ - V₁ ) = 3,03.10⁵.( 6,5 -2,5 )

W = 12,12.10⁵ J

4)

[tex]W = P.(V_B-V_A )[/tex]

[tex]W = 2.10^5(15.10^{-6}-5.10^{-6})\\W =2 J[/tex]
