gas helium sebanyak 16 gram memiliki volume 5 liter dan tekanan 2 X 10 pa jika R=8,31j/molk

massa gas helium, m = 16 gram
Mr He = 4 gram/mol
Volume, V = 5 liter = 5 x 10⁻³ m³
Tekanan, P = 2 x 10⁵ Pa
R = 8,31 J/mol. K

Tanya : Suhu, T = ___?

jawab :

P.V = n.R.T
P.V = (m / Mr). R. T

T = (P.V. Mr) / (m. R)
 
T = (2 x 10⁵ x 5 x 10⁻³. 4) / (16 x 8,31)

T = 4000 / 132,96

T =  30,08 Kelvin
