Question

Dalam ruangan yang volume nya 1,5 liter terdapat 2,0 gram gas jika kelajuan rata-rata partikel gas 1500 m/s maka tekanan gas adalah.... (tolong pake cara)

Answer 1

Diket:
V = 1,5 liter = 1,5x10⁻³ m³
m = 2 gram = 2 x10⁻³ kg
vrms = 1500m/s
Dit: tekanan gas (P).....?
ρ = m/V
ρ = 2x10⁻³/1,5x10⁻³
ρ = 2/1,5 = 4/3 kg/m³
,
v² = 3P/ρ
1500² = 3P/4/3
(15x10²)² = 9P/4
225x10⁴ = 9P/4
9P = 4x225x10⁴
9P = 900x10⁴
P = 900x10⁴/9
P = 100x10⁴
P = 1x10⁶ pa
