Interpretation:
The relation between the theory of conservation of mass and the Dalton`s theory of the atoms needs to be explained.
Concept introduction:
The elements are made up of atoms and atoms are the smallest particle that is not visible through naked eyes.

Answer to Problem 4SSC
According to the law of conservation of mass, matter can neither be created nor destroyed in a closed system.
Explanation of Solution
Dalton’s atomic theory is based on two laws, the first is the law of conservation of mass and the second law is the law of definite proportions.
Dalton’s hypothesis stated that the study of atoms can be used to explain the law of conservation of mass and the law of definite proportions. The theory explains that the matter is made up of small, indivisible particles known as atoms.
Hence, Dalton’s theory states that all the matter comprises of indivisible atoms and each atom of a particular element has equal mass, also the properties of each atom is same.
