(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.
(b)
Interpretation:
The sample of a sugar molecule 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.
(c)
Interpretation:
The sample of a blade of grass 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 particulate level includes samples of tiny particles that make up matter.
(d)
Interpretation:
The sample of a helium atom 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.
(e)
Interpretation:
The sample of a single-celled plant too small to see 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.
