In very hot situations like an industrial klin, there is risk of melting of wires if they are made up of metal with low melting point. Also, metal with high electrical conductivity is required under such situations.
Graphite is good conductor of heat and electricity also, it has very high melting point therefore, it is used instead of copper and gold with low melting point to make wires.
Other advantages of graphite are it is thermal shock resistant, The coefficient of thermal expansion is 3 times less than that of copper. The melting of graphite does not take place and it gets converted directly from solid to liquid at 3400 °C (extremely high temperature). It forms lighter electrode because density of graphite is 5 times less than that of copper.
If you were to plug your nose, it would block out more than 80% of taste, causing all three items to have no taste- therefore making them taste the same.
Answer: In the chemical formula for water, the subscript for hydrogen is 2. Notice that the 2 is smaller and written slightly below the H and O. It is called a subscript because it is written ("script") "below" ("sub") the preceding letter.
Standard Molar Volume is the volume occupied by one mole of any gas at STP. Remember that "STP" is Standard Temperature and Pressure. Standard temperature is 0 &176:C or 273 K. Standard pressure is 1 atmosphere or 760 mm Hg (also called "torr"). 1 mole of any gas at STP occupies 22.4 liters of volume.
