How much energy transferred when we burn a piece of wood ?

  1. Jul 27, 2015 #1
    Hi All,
    If we burn a piece of wood having mass 1 Kg, in a closed surrounding (Box),
    If box is 1 cubic meter in size and box is perfectly heat insulated .
    Will all energy of wood , say 3,890 K cal/Kg , get transferred to air surrounding it ?
    How much temperature rise of the air will occur?

    Thanks in advance.

    If the box is closed then some of the wood will burn, but very quickly all of the Oxygen will be used up and it will cease burning.

    Look up "heat capacity". That is the key concept you need to answer this question.
