Non-Metal Question 1:
Select the non-metal from the following :
Answer (Detailed Solution Below)
Non-Metal Question 1 Detailed Solution
The Correct answer is Sulphur.
Key Points
- Sulphur is a non-metal and is present in the periodic table under the category of non-metals.
- It is a bright yellow solid at room temperature, widely known for its distinctive odor when burned.
- Sulphur is an essential element for all living organisms, playing a vital role in the formation of proteins and enzymes.
- It is found in nature in both its elemental form and as part of various compounds, such as sulphates and sulphides.
- Industrial applications: Sulphur is used in the production of sulfuric acid, which is one of the most widely used chemicals in the world. Sulfuric acid is critical for the manufacture of fertilizers, explosives, and other industrial products.
- Biological significance: Sulphur is a component of several amino acids like methionine and cysteine, which are building blocks of proteins.
- It is used in vulcanization of rubber, making it more durable and elastic.
- Sulphur also plays an important role in agriculture as it is a key element in plant nutrition, helping in the synthesis of chlorophyll and improving crop yield.
Additional Information
- Iron
- Iron is a metal and is classified as a transition element in the periodic table.
- It is widely used in construction, manufacturing of steel, and other industries.
- Biological significance: Iron is essential for human health as it is a key component of hemoglobin, helping in oxygen transport within the body.
- Sodium
- Sodium is a metal and is classified under the group of alkali metals in the periodic table.
- It has a wide range of applications, including its use in the production of chemicals like sodium hydroxide and table salt (sodium chloride).
- Biological significance: Sodium is crucial for the functioning of the human nervous system and maintaining fluid balance in the body.
- Copper
- Copper is a metal and is classified as a transition element in the periodic table.
- It is widely used in electrical equipment due to its excellent conductivity.
- Biological significance: Copper is essential for human health as it plays a role in the functioning of enzymes and in the production of red blood cells.
Non-Metal Question 2:
Identify the non-metal, having high thermal conductivity.
Answer (Detailed Solution Below)
Non-Metal Question 2 Detailed Solution
Concept:
Non-metal:
- Non-metals are the elements that form negative ions by accepting or gaining electrons.
- Non-metals usually have 4, 5, 6 or 7 electrons in their outermost shell.
- Non-metals are those which lack all the metallic attributes. They are good insulators of heat and electricity.
- They are mostly gases and sometimes liquid.
- Some of then are even solid at room temperatures like Carbon, sulphur and phosphorus.
Thermal Conductivity:
- Thermal conductivity refers to the ability of a given material to conduct/transfer heat.
- It is generally denoted by the symbol ‘k’ but can also be denoted by ‘λ’ and ‘κ’.
- The reciprocal of this quantity is known as thermal resistivity.
- Materials with high thermal conductivity are used in heat sinks whereas materials with low values of λ are used as thermal insulators.
- The law of heat conduction states that the rate at which heat is transferred through a material is proportional to the negative of the temperature gradient and is also proportional to the area through which the heat flows.
- The differential form of this law can be expressed through the following equation: q = - k ΔT, where k = thermal conductivity, ΔT = temperature gradient, q = heat flux
Explanation:
- The thermal conductivity of wood is generally within the range of 0.1–0.2 W/mK.
- The thermal conductivity of water is 0.598 W/m·K at 20°C.
- The thermal conductivities of the ice samples prepared by the 0% CAS and 50% CAS air-blast freezing methods measured at −29°C are both 2.75 ± 0.03 W/(m·K).
- Bricks possess a low thermal conductivity which averages between 0.5 – 1.0 W/(m/K).
- Hence, the ice has a higher thermal conductivity.
