theory
Macroscopic properties can be observed and measured on a larger scale, such as mass, volume, and pressure, while microscopic properties pertain to the individual particles that make up a substance, such as molecular structure and behavior. Macroscopic properties describe the overall behavior of a system, whereas microscopic properties provide insight into the interactions between particles at a molecular level.
a hypothesis.what is logical explanation for events observed in natureA hypothesis
A theory can offer explanation for an observed phenomenon that is supported by extensive data.
Around 1900, there was a huge debate amongst scientists on whether the molecular hypothesis of nature -- ie that matter consisted of moving particles -- was something worthy of study. Basically, there was no experiment that had a result that required the existence of molecules. For that reason, many (if not most) scientists thought that only macroscopic, measurable entities (pressure, temperature) should be studied. Einstein showed that the Brownian Motion of small dust particles could only be explained as the random strikes of molecules in the atmosphere against the dust particle. Assuming the existence of molecules made the explanation of Brownian Motion trivial, assuming the opposite made an explanation impossible.
Macroscopic changes refer to changes that can be observed with the naked eye. This may include changes in shape, size, color, or state of matter. For example, melting of ice, rusting of metal, or growth of a plant are all examples of macroscopic changes.
law and theory
A hypothesis.
In the scientific sense atleast, the word's usually used as a distinction from microscopic. Microscopic features are observed under a microscope, but macroscopic features are observeable by the human eye.
A scientific theory is an accepted and universally true explanation of observed facts that is based on evidence, tested through experimentation, and widely accepted by the scientific community.
A law can offer an explanation for an observed phenomenon that is considered to be universally true.
A Guess...!
