Question

Is cutting a log for firewood a physical or chemical change?

1) Physical change
2) Chemical change

Answer 1

Cutting a log for firewood is a physical change that alters the shape and size of the log without changing its chemical composition.

Step-by-step explanation:

The process of cutting a log for firewood is a physical change. Cutting a log for firewood is a physical change that alters the shape and size of the log without changing its chemical composition.

A physical change is a change that does not alter the chemical composition of a substance. In the case of cutting a log for firewood, the log is being physically altered in shape and size but the chemical composition of the wood remains the same.

An example of a chemical change would be if the log was burned, which would result in the release of heat and gases as the wood undergoes a combustion reaction.
