Mass Spectrometry

This process is an instrumental method in which a sample is changed to fast moving positive ions by electron bombardment. The charged particles vary due to their different mass to charge ratio and are estimated with the help of this difference. It is also called mass spectroscopy.

10 Find the transition time of 20g naphthalene with the surrounding temperature as 30oC.Let the boiling tube has mass 25 g, diameter 2.5 cm and thickness 0.15cm. How much time does 30g of ice takes to melt at a surrounding temperature of -50C. (We are using a boiling tube having mass= 20g, radius=1.5cm, thickness=0.2cm.) In the above experiment, let the surrounding temperature is changed to 0oC. What will be the change in the transition time for ice? Repeat the experiment for different surrounding temperatures and study the variation of melting point of ice. Calculate the melting point of wax having a mass 30g. Let we are using a boiling tube of mass 25g, having a thickness 0.5 cm and radius 1.5 cm.( Choose surrounding temperature as 40oC)
