The form which the word takes in English is a substantival use of the 3rd person singular of the present indicative of the Latin verb, and is due to a similar use in French of the older interest, modern interet.
The sensation of different colours depends on the different frequency of vibrations excited by the light in the retina.
The medieval lawyers used the phrase damna et interesse (in French dommages et interets) for such compensation by way of damages for the non-fulfilment of a contract, and for damages and indemnity generally.
This term[1] and the ideas underlying it were introduced into optics by Thomas Young.
When interest is awarded by a court it is generally at the rate of 4%; under special circumstances 5% has been allowed.
But when it has been the constant practice of a trade or business to charge interest, or where as between the parties interest has been always charged and paid, a contract to pay interest is implied.
Important historical instances of the use of the interdict occur in the cases of Scotland under Pope Alexander III.
Much of the copper of commerce is made from chalcopyrite and bornite, and these ores are more difficult to work.
The primary deposition was of chalcopyrite and other copper sulphides, together with garnet, diopside, and other minerals known to have required high temperature in their formation.
Copper is known to be taken into solution as copper sulphate at the surface, and to be redeposited as chalcocite where these sulphate solutions come in contact with chalcopyrite or pyrite below.
The ores are in lenticular bodies, and consist of almost massive pyrite with a small amount of quartz and scattered grains and threads of chalcopyrite (copper-iron sulphide).
Not only has the process been duplicated in the laboratory, but the common coating of chalcocite around grains of pyrite and chalcopyrite below the water level indicates that this process has been really effective.
Owing to the frequent presence of mechanically admixed chalcopyrite and chalcocite, the published analyses of erubescite show wide variations, the copper, for example, varying from 50 to 70%.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "chalcopyrite" in a variety of sentences. We hope that you will now be able to make sentences using this word.
