(a) Interpretation: The sample of human skin cell is whether a macroscopic, microscopic or particulate matter is to be identified. Concept introduction: The macroscopic system includes samples of matter those are visible with the naked eye. The microscopic system includes matter those cannot be seen by the naked eye. The microscopic matter requires an optical microscope to be seen. The particulate level includes samples of tiny particles that make up matter. The sample of matter at particulate level is too small to be seen with the most powerful optical microscope.
Solution Summary: The author explains that the sample of human skin cell is a microscopic matter.

The total weight of copper in a vehicle ranges from 15 kilos for a small car to 28 kilos for a luxury car.
As a material scientist you are analyzing a luxury car that has 30 kilos of copper.
What does this indicate about the car’s performance?
Where is copper (Cu) likely to be located in the car? Discuss the physical and chemical properties of copper in your answer.
Identify the following samples of matter as macroscopic, microscopic, or particulate: (a) a human skin cell; (b) a sugar molecule; (c) a blade of grass; (d) a helium atom; (e) a singlecelled plant too small to see with the unaided eye.
The average micro-nano plastic concentration in bottled water was about 2.4×10^5 particles per liter of bottled water, about 90% of which were nano-sized particles. Assuming that each nanoparticle can be approximated as a sphere with a diameter of 100 nm and that the average density of nanoparticles is 1.2 g/cm^3, estimate the mass of nanoparticles ingested if someone drinks all of their recommended 64 fluid ounces of water per day via bottled water every day for a year. Provide your answer is units of nanograms (ng).
