Mass Spectrometer When you hear the words mass spectrometer‚ what do you think of? To some people‚ these words do not have any meaning; however the mass spectrometer has a great significance. The mass spectrometer has been a universal research tool‚ mostly involved in comparing the masses of atoms. Since the invention of this tool about 100 years ago‚ the mass spectrometer has been responsible for the description of molecular structure‚ the detection of isotopes‚ the classification of atomic

Mass production refers to the making of large quantities of standardized products. The process involves division of labour and each worker specializes in one or two tasks‚ doing repetitive work. On the other hand‚ the craftsman is the expert who is solely responsible for all the steps involved in producing the product. There is assumption that the craftsman is the master who has skill‚ and expertise to ensure that all his products are of a good quality. Whether mass production will inevitably lead

Mass Spectroscopy Mass spectroscopy is a method used in science and industry in order to obtain the masses and relative concentrations of atoms and molecules and to detect isotopes in a sample based on their masses. In order to do this the method requires an instrument called the ‘mass spectrometer’‚ of which‚ is able extract accurate information of the relative masses of isotopes and their relative abundance. This makes the mass spectrometer very useful for applications such as carbon dating

The main objective is to demonstrate the law of Conservation of Mass. Use Vinegar and baking soda to demonstrate the law of Conservation of Mass. Introduction: The law of Conservation of Mass states that mass is neither created nor destroyed during ordinary chemical reactions or physical changes‚ which means that no matter how dramatic of a change that a substance goes through‚ it will not lose mass. It may seem like it lost mass‚ and usually‚ if you weighed the result‚ it will have a different

each successive means of transport has made the world smaller and more accessible. In fact‚ mass tourism has become one of the most controversial subjects in the world today. Although it possesses several advantages‚ mass tourism might have negative impacts on local culture and the environment. Many people emphasize the benefits that human society could have from the generous idea of tourism. Mass tourism creates more employment for the locals that could be a great help in bringing up the

and political changes which continue to affect our society today. These changes all revolve around the new concept of mass democracy‚ in which the common man or farmer controlled the vote and the way things were ran in government. This was made possible by the new reduced voting restrictions that gave all white males the right to vote‚ and not just wealthy land owning white males. Mass democracy’s formation led to new campaigning strategies for politicians‚ newly formed political parties which played
