What is the origin of Tungsten?
Tungsten occurs naturally on Earth. It is expected to have been produced by the same supernovae that produced our other heavy elements. It was first identified by Johan Gottschalk Wallerius in 1747. There are mines in Europe and China that produce most of it. A few mines in North and South America. I hope I guessed which "origin" you intended...
Who is the scientist that discovered the law of evaporation?
When a liquid is placed in an open vessel, it slowly escapes into gas phase, eventually leaving the vessel empty. This phenomenon is known as evaporation. Evaporationof liquids can be explained in terms of kinetic molecular model. Although there are strong inter-molecular attractive forces which hold molecules of a liquid together, the molecules having sufficient kinetic energy can escape into gas phase if such molecules happen to come near the surface. In a sample of liquid all the molecules do not have same kinetic energy. There is a small fraction of molecules which have enough kinetic energy to overcome the attractive forces and escape into gas phase. Evaporation causes cooling. This is due to the reason that the molecules, which undergo evaporation, are high-energy molecules; therefore the kinetic energy of molecules which are left behind is less. Since the remaining molecules have lower average kinetic energy therefore, temperature must be lower. If the temperature is kept constant the remaining liquid will have the same distribution of molecular kinetic energies and the high-energy molecule will keep on escaping from the liquid into the gas phase. If the liquid is taken in an open vessel, evaporation will continue until whole of the liquid evaporates.* Three petridishes of diameter 10 cm with covers * 10 ml pipette * Stop watch * Acetone * Benzene * Chloroform * Clean and dry the petridishes and mark them as A, B, C. * Pipette out 10 ml of acetone to petridish A and cover it. * Pipette out 10 ml of benzene in petridish B and cover it. * Pipette out 10 ml of chloroform in petridish C and cover it. * Uncover all the three petridishes simultaneously and start the stop-watch. * Note the respective time when the liquids evaporate completely from each petridish.

What is an evaporating dish and how is it used?
The evaporating dish is used to heat and evaporate liquids.This porcelain item resembles a shallow bowl with a spout. Evaporating dishes are traditionally used to evaporate solvent to concentrate a solution; however they can also be used to hold sand for a sand bath, as a small water bath, or as a drying dish (like a watch glass).If heated by a direct flame, it will often be placed on a clay triangle for support.
