(a)
Interpretation:
Whether microwave is a matter or not needs to be identified.
Concept introduction:
Everything in this universe is made up of materials which scientist have named matter. Food, air, cloths, stone, etc. are matter.
Answer to Problem 92A
Microwave is not considered as a matter.
Explanation of Solution
Matter has mass and it occupies space. It is made up of particles. Particles of matter are continuously moving. Microwave does not have any mass thus, it is not considered as a matter.
(b)
Interpretation:
Whether helium inside a balloon is a matter or not needs to be identified.
Concept introduction:
Everything in this universe is made up of materials which scientist have named matter. Food, air, cloths, stone, etc are matter.
(b)
Answer to Problem 92A
Helium is considered as a matter.
Explanation of Solution
Helium is made up of proton, electron and neutron. It is an element; each of the particle of helium has mass. Thus helium is considered as a matter.
(c)
Interpretation:
Whether heat of the sun is matter or not needs to be identified.
Concept introduction:
Everything in this universe is made up of materials which scientist have named matter. Food, air, cloths, stone, etc are matter.
(c)
Answer to Problem 92A
Heat of the sun is a not considered as a matter.
Explanation of Solution
Heat has no mass. It is a form of energy. Thus it is a not considered as a matter.
(d)
Interpretation:
Whether velocity is a matter or not needs to be identified.
Concept introduction:
Everything in this universe is made up of materials which scientist have named matter. Food, air, cloths, stone, etc are matter.
(d)
Answer to Problem 92A
Velocity is not considered as a matter.
Explanation of Solution
Velocity is a measurement. It is used to movement of an object. Velocity has no mass and volume. Thus it is not considered as a matter.
(e)
Interpretation:
Whether speck of dust is a matter or not needs to be identified.
Concept introduction:
Everything in this universe is made up of materials which scientist have named matter. Food, air, cloths, stone, etc are matter.
(e)
Answer to Problem 92A
A speck of dust is considered as a matter.
Explanation of Solution
A speck of dust has mass and it occupies space. It is very small particle. Thus a speck of dust is considered as a matter.
(f)
Interpretation:
Whether blue color is a matter or not needs to be identified.
Concept introduction:
Everything in this universe is made up of materials which scientist have named matter. Food, air, cloths, stone, etc are matter.
(f)
Answer to Problem 92A
The color of blue is not considered as a matter.
Explanation of Solution
Color has no mass and space. The color of blue has wavelength, frequency and energy. Thus it is not considered as a matter.
