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.
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.
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.
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.
Yes, all substances have unique boiling and freezing points that are determined by their chemical composition and properties. These points represent the temperature at which a substance changes its state from liquid to gas (boiling point) or from liquid to solid (freezing point).
The lines should never touch, they should only include the correct numbers between them, and they must always close.
An impure sample will have a lower melting point, and will also have wider melting point range than that of a pure sample of the same substance. a sharp melting point range can also indicate a eutectic mixture
refrigerate poop, never heard of it but you could. i guess

Hopefully never.
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.
It's on now and I'm watching it, so obviously it has been repeated
There are no examples for D-Day, it was a unique event, never repeated.
no.the particle never disappear,the water just change its properties of particles when melting to ice
Not every question can be easily answered.
The symbol "D" can never be repeated in Roman numerals. According to the traditional rules of Roman numerals, "D" represents the number 500. It cannot be repeated to represent larger numbers, such as 1000 or 5000.
My mum told me never talk to strangers.
Packets are never repeated in a network because information in their headers will always change (sequence id, checksums, etc.). The data may be repeated, but that is only a part of the packet.
