What does “conservation of matter” mean? ANSWER. The phrase “conservation of matter” describes how the amount of matter stays the same, even if it changes form. After Video When the team mix 25 grams of sugar into 150 grams of water, the sugar seems to disappear! Where does it go? ANSWER. The sugar dissolves into the water.

Experiments in which a mass change is observed - where there doesn't seem to be conservation of mass, we need an explanation! Reactions that do not go to completion might give false results and if the reaction involves a reacting gas OR a gaseous product it is difficult to make accurate measurements to confirm the validity of the law of conservation of mass. Conservation of Mass. In this GCSE Chemistry video we look at conservation of mass. We explore why mass is always conserved in chemical reactions. We then learn how to calculate the masses involved in chemical reactions.

This law was later amended by Einstein in the law of conservation of mass-energy, which describes the fact that the total mass and energy in a system remain constant. This amendment incorporates the fact that mass and energy can be converted from one to another. Understanding conservation of mass allows understanding of balancing equations and calculating reaction masses.

The basic principle students should observe and conclude is that mass is conserved in these processes, so the mass should not change. Students may observe slight variations of plus or minus 0.1 grams, depending on the sensitivity of the balance or whether the mass is actually somewhere between two values.
