Diket: T = 3000 K k = 1,38x10⁻²³ j/k Dit: Ek rata2.....? Ek = 2/3 k T Ek = 2/3 x 3000 x 1,38 x10⁻²³ Ek = 2 x 1000 x 1,38 x10⁻²³ Ek = 2 x 10³ x 1,38x10⁻²³ Ek = 2,76 x10⁻²⁰ J
T = 3000 K
k = 1,38x10⁻²³ j/k
Dit: Ek rata2.....?
Ek = 2/3 k T
Ek = 2/3 x 3000 x 1,38 x10⁻²³
Ek = 2 x 1000 x 1,38 x10⁻²³
Ek = 2 x 10³ x 1,38x10⁻²³
Ek = 2,76 x10⁻²⁰ J
