Classify the following materials in three ways each ( on the basis of their properties).
(a) Wood
(b) Glass
(c) Paper
(d) Iron
Answers
Answer:
wood is used as fuel
glass is making window.
paper is making different books .
iron is used as natural sources of metal.
Answer:
The three ways they differ based on the properties are
Wood - opaque, color, sound-electro-thermal conductivity.
Glass - transparent. colorless (white), heat resistance.
Paper - translucent - opaque, various colors,
Iron - opaque, silvery-white hue, conducts heat and electricity.
Explanation:
a. Wood:
Color, luster, texture, macro-structure, odor, moisture, shrinkage, internal tensions, swelling, cracking, warping, density, and sound-electro-thermal conductivity are some of the key physical characteristics of wood.
About 50% of wood's elemental composition is carbon, followed by 6% hydrogen, 44% oxygen, and traces of numerous metal ions.
b. Glass:
Transparency, heat resistance, pressure and breakage resistance, and chemical resistance are among glass' primary properties.
Stabilizers, fluxes, and formers are typically found in glass.
c. Paper: Basis weight, thickness, density, two-sidedness, smoothness, permeability, handling, stiffness, roughness, and porosity all affect the physical qualities of paper sheets, which in turn affect their softness, hardness, compressibility, dimensional stability, curl, and strength.
A typical paper-based product has 90–99 per cent cellulose fibers, which are both the main structural element and the factor that has the greatest impact on the product's final qualities.
d. Similar to other metals, iron has a shine, conducts heat and electricity, and produces positive ions during chemical reactions. Pure iron is relatively malleable and may be heated up without difficulty. It has a silvery-white hue. Iron may be attracted quickly (can be magnetized).
Fe represents the chemical element iron. It is a member of group 8, period 4, on the periodic table. It has the atomic number 26. Iron metal has a greyish hue and is extremely malleable and ductile. In humid air and at high temperatures, but not in dry air, it starts to rust. It is chemically active and dissolves easily in weak acids.
