Once a sample has been melted, it may have decomposed slightly. Contamination with a decomposed product will change the MP of the sample, so a fresh sample must always be used for each new test.

How clean is well water?

If your family is drinking it, you should never guessabout that ! Take a sample to a lab and get it tested so you KNOW how clean (or not) it is.If your family is drinking it, you should never guess about that !Take a sample to a lab and get it tested so you KNOW how clean (or not) it is.


What is the melting point of copper pipe?

The melting point of copper is approximately 1,984°F (1,085°C), but this can vary slightly depending on the specific composition of the copper alloy used in the pipe. It is important to note that the melting point of copper pipe should never be reached during regular use, as it could lead to structural failure and potential safety hazards.


Why are the melting and boiling points of air never given?

Air is a mixture; it doesn't have a melting or boiling point. It has a mixture of carbon dioxide, ozone, oxygen, nitrogen, helium, etc. look up those gases separately and you will get answers.


Do all substances have their own boiling point and freezing point?

please correct me if im wrong but i think everything that doesnt burn has a melting point Everything has a melting point, no matter how hard or dense. Even diamonds can melt if hot enough. Not everything has a melting point. Some things never change into liquid, they go from solid to gas. Dry Ice does this at room temperature. This process is called sublimation.

Why should the maximum percent yield never be above 100?

Because the yield can never exceed the quantity in the original mix. ie if an ore sample contains 3% of a mineral, if that 3% is extracted totally, then the yield is 100% and cannot be more because that's all there is in the sample.
