Why should you always use a new capillary tube with a sample of your compound
when doing a second melting point determination?
i have searched a lot about this in the internet but i ended up nothing...

Because you may have generated a new crystal modification, which has a different MPt.
Or the compound may have decomposed.
Capillary tubes are not expensive

THANK YOU SO MUCH!i have some other question regarding melting points..
which has a wider melting range , a mixture or a pure substance?

what is the effect of the impurity of the boiling point of a substance?
some of my sources said that i will increase and some told me that it will decrease...
