- Ech = Chemische energie
m = massa in g
V = volume in cm^3
r = stookwaarde/verbrandingswarmte
in J/g of J/cm^3
Yvette heeft 2,8kg hout en steekt dit in brand.
Hoeveel energie levert dit op?
m = 2,8 kg = 2.800g
r = verbrandingswaarde van hout opzoeken in BINAS
r = 16.000J / g
Ech = r x m
Ech = 16.000 x 2.800 = 44.800.000 J = 44,8MJ
