Question

Wood with a mass of 3.0 grams was burned in an open dish. The ashes weighed 1.2 grams.

What happened to the rest of the wood? B
A

Answer 1

The rest of the wood was burned into gases of equivalent weight.

Step-by-step explanation:

The rest of the wood was burned into gases of equivalent weight.

• When wood is burnt in the open air, with the help of oxygen and heat, it is transformed into carbon dioxide, water vapor, and ashes.

• Ignition and combustion of wood mainly depend on pyrolysis which is also known as thermal combustion.

• The loss in weight of the ashes is due to the fact that gases and water vapor are also formed due to the combustion of wood.
