SODIUM gSodium is a chemical element with the symbol Na (from Latin: natrium) and atomic number 11. It is a soft‚ silver-white‚ highly reactive metal and is a member of the alkali metals; its only stable isotope is 23Na. The free metal does not occur in nature‚ but instead must be prepared from its compounds; it was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. Sodium is the sixth most abundant element in the Earth’s crust‚ and exists in numerous minerals such

ceramics‚ Yttria partially stabilized Zirconia (YPSZ) is being favoured for diesel engines since its co efficient of thermal expansion is close to those of metals used in piston. This avoids problems relating to difference in thermal expansion between metallic and thermal parts which also increases its durability. Compared to the conventional engine (without coating over the piston crown) the modified engine (with ceramic coating over the piston crown) did not produce any observable knock in the engine

The Yellow-Billed Jacamar is commonly about 18-21 centimeters in height and 16-24 grams in weight‚ although it may vary. The Yellow-Billed Jacamar has a copper colored chest and a dark metallic green coat on it’s wings and back. The head is half black and half green and the coppery chest and black head makes the Yellow-Billed Jacamar look very similar to a North-American Robin. The beak of the Yellow-Billed Jacamar is very long in order to catch insects out of the air and on the ground. The Yellow-Billed

Jarriette kenn D Patenio Jaymar patana Job madronal Do all ideal gases have the same molar volume? An ideal gas has the following equation of state (an equation which relates various thermodynamic properties for a substance‚ such as pressure‚ temperature and molar volume): Pv = RT P - pressure v - molar volume R - universal gas constant T - absolute temperature Clearly the molar volume depends on temperature and pressure‚ so if two gases are at different conditions then they

Secondly‚ asbestos is the pollutant which has cancer-causing properties when inhaled‚ it can cause illnesses such as asbestosis and many type of cancer. Thirdly‚ lead and mercury are metallic elements and can cause environmental and health problems for humans and animals. It’s even more poisonous. It’s usually very hard
