simple reasoning

1. why is the law of conservation of mass considered a significant discovery?

a. it shows that mass always increases in a closed system.
b. it explains how to create matter.
c. it proves that energy can be created from mass.
d. it helps scientists understand how matter works.
strategic thinking

1. based on the reading passage, how does the law of conservation of mass influence scientific understanding?

a. it provides a fundamental rule for understanding matter and its transformations.
b. it primarily affects the study of mechanics by defining force interactions.
c. it limits the scope of fluid dynamics by restricting the movement of matter.
d. it complicates chemical reactions by introducing unpredictable mass variations.

Explanation:

1. According to the law of conservation of mass, matter is not created or destroyed but rearranged when it changes forms.
2. Antoine Lavoisier discovered the law of conservation of mass.
3. When a piece of paper is burned, the atoms are rearranged (following the law of conservation of mass).
4. During the burning of wood (a chemical reaction), atoms are rearranged (law of conservation of mass principle).
5. The law of conservation of mass helps scientists understand how matter works as it shows matter behavior in reactions etc.
6. The law of conservation of mass provides a fundamental rule for understanding matter and its transformations.

Answer:

1. D. It is rearranged.
2. C. Antoine Lavoisier
3. C. A piece of paper is burned.
4. D. The atoms are rearranged.
5. D. It helps scientists understand how matter works.
6. A. It provides a fundamental rule for understanding matter and its transformations.
