Write Difference between following
a. Fertilizer and manure
b. Thermoplastic and thermosetting plastic
c. Metals and non metals
d. Communicable and non communicable disease
e. biodegradable and non biodegradable substance
Answers
Answer:
a:Manure is a natural fertilizer. To make manure, decomposition of plants and animal waste is done by farmers. The product of this decomposition is a material rich in organic matter which we call manure. Instead, it gives fertility to the soil by adding humus (an organic component of the soil). ...
B:The primary difference between the two is that Thermoset is a material that strengthens when heated, but cannot be remolded or heated after the initial forming, while thermoplastics can be reheated, remolded, and cooled as necessary without causing any chemical changes.
High mechanical property: Poor thermal conductivity for housing replacements
Thermoset Pros2: Thermoset Cons2
More Resistant against high temperature: Cannot be recycled
C:Non- metals are brittle (break easily). They are neither malleable nor ductile. Metals are good conductors of heat and electricity.
...
02 Acid, Bases and Salt.
Metals Non-Metals
Metals form basic oxides. Non-metals form acidic oxides or neutral oxides
D:A non-communicable disease (NCD) is a disease that is not transmissible directly from one person to another. NCDs include Parkinson's disease, autoimmune diseases, strokes, most heart diseases, most cancers, diabetes, chronic kidney disease, osteoarthritis, osteoporosis, Alzheimer's disease, cataracts, and others.
E:Biodegradable substances are those that degrades or break down naturally. Non-biodegradable substances are those that do not degrade easily. ... The environment in which we live is surrounded by these two things only, even the materials we use in day to day life can be biodegradable or non-biodegradable.
