Expert Solution & Answer
Interpretation Introduction
To predict the given photograph and illustrations of table salt, identify the depiction of matter at the macroscopic, microscopic, and/or particulate levels with explanation.
Interpretation:
Macroscopic, microscopic and particulate forms of matter are the three forms of matter.
Macroscopic can be viewed by the naked eyes, but we will be able to view microscopic form only by an optical microscope or electron microscope. Matter at the particulate level is so small that even with electron microscope it is really very difficult see them. Scientist use model to understand matter at particulate level. Models is representation of something
Concept introduction:
Answer to Problem 2.1TC
The art depicts a model of table salt at the particulate level. The photograph shows the macroscopic level
Explanation of Solution
Macroscopic, microscopic and particulate forms of matter are the three forms of matter.
Macroscopic can be viewed by the naked eyes, but we will be able to view microscopic form only by an optical microscope or electron microscope. Matter at the particulate level is so small that even with electron microscope it is really very difficult see them. Scientist use model to understand matter at particulate level. Models are representation of something. From the above statement we can say that the art depicts a model of table salt at the particulate level. The photograph shows at the macroscopic level
Conclusion
Thus the art depicts a model of table salt at the particulate level. The photograph shows the macroscopic level
