What happens to the entropy of a piece of wood as it is burned?

It increases in value positively

Explanation:

The entropy of a chemical reaction can be defined as the degree of disorderliness. Hence when we talk about entropy, we are talking about the degree of randomness associated with that specific chemical reaction. The burning of wood is a kind of spontaneous reaction.

For a reaction to be spontaneous, the change in free Gibbs energy must be negative. To make this a reality, at constant enthalpy, the reaction temperature and change in entropy is expected to be negative in value. To get this negative value needed, it is essential know that the value of the entropy must increase as the temperature of the burning wood is increasing too.
