The total energy released per gram of methane burnt is 119,941.3 J/g.
Energy absorbed by water
Q = mcΔθ
where;
- m is mass of water
- c is specific heat of water
- Δθ is change in temperature
Q = (500)(4.184)(68 - 25)
Q = 89,956 J
Total energy released per gram of methane burnt
0.3T = 89,956 J
T = 89,956 J/0.3
T = 299,853.3 J
Total energy per gram of methane, E = T.E/m
E = (299,853.3 J) / (2.5 g)
E = 119,941.3 J/g
Thus, the total energy released per gram of methane burnt is 119,941.3 J/g.
