the law of conservation of mass
Count the atoms in each substance in the reactants and products. (Apex)
You add or change the coefficient, never the subscript or it becomes a completely different molecule.*cough 8th grade science*
physical change
A physical change is a change in chemical composition. A physical change is a change where chemical composition is not altered. Not all chemical changes are accompanied by a physical change, but some are. The same is true for the reverse.
the law of conservation of mass
Chemical science, because yeast is irreversible. Chemical Change: Irreversible Physical Change: Reversible
that they are both science but in physical science they talk about physical changes and chemical changes
Chemical science is the study of chemical changes, i.e. changes that involve electron transfer, bond formation and the thermodynamics and kinetics involved in these changes. Physical science is a broader term that encompasses the study of natural phenomena. Chemical science can be considered as a part of physical sciences.

Chemical and physical changes are part of methods applied in science.

Chemical energy
Physics relates to every science because it is the basis of the universe. Because everything is based on science, so is chemistry (i.e. the bonds between molecules are physical, not chemical). And all of biology is chemical, so therefore on the most basic level it is also physical.
