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. Petridish MarkLiquid TakenTime taken for complete evaporation A Acetone 53 min B Benzene 42 min C Chloroform 30 min The rate of evaporation of the given three liquids is in the order: Chloroform > Benzene > Acetone
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.
When was Nils Wallerius born?
Nils Wallerius was born in 1706.
When did Nils Wallerius die?
Nils Wallerius died in 1764.
Who is the scientist that discover evaporation?
Nils Wallerius - Swedish - between 1739-1747 A.D.
Who was Nils Wallerius and why was his discovery of evaporation important?
Nils Wallerius was a Swedish scientist who discovered the process of evaporation in the 18th century. His discovery was important because it helped to further the understanding of the water cycle and how water moves between the Earth's surface and the atmosphere. This knowledge is crucial for various fields such as meteorology, agriculture, and environmental science.

How did nilis wallerius discover evaporation?
Niels Wallerius did not discover evaporation. The process of evaporation has been observed and understood since ancient times. Evaporation is a natural phenomenon where liquid water transforms into vapor due to heat energy.
