Law of Conservation of Mass Experiment
Material(s) Mass (g)
Mass of test tube 42.78
Mass of steel wool 0.70
Mass of steel wool & test tube (original) 43.48
Mass of steel wool & test tube (after burning) ?

Students conduct an experiment in which steel wool is burned in a closed test tube.

The steel wool reacts with an amount of oxygen equal to 1.43% of the mass of the steel wool. What is the correct value for the missing mass in the table?

in most common fires, oxygen is needed for an oxidation reaction to takes place. the combination of oxygen with any element as fuel can create fire and combustion will occur especially if wood, light materials and other combustible things are combine with oxygen.

explanation:

to push or pull an object in a certain direction is known as force. a force in moving an object from one place to another.

force depends on the mass of an object. so, more is the mass of an object more will be the force required to move the object.

thus, we can conclude that the use of force to move an object is push or pull.
