When you burn coal does the mass stay the same?
Your question isn't rigorous enough. When you burn coal you are combining carbon from the coal with oxygen in the air. So the mass of Carbon Dioxide created is greater than the original mass of coal. There is no mass destroyed however, you just have to be more rigorous in the parameters of your question.
Does coal sink or float?
coal washing is done using the property that coal floats in water while other mineral matter sink in water. The jig that oscillates with coal and water in it actually skims the coal from the top and drains the ash, pyrites and stones at the bottom. Depending upon the intricacy of included minerals in the lumped mass, the matter occupies suspended positions; when broken, the coal floats and other materials sink. Hence, a coal washery has a crusher preceding the jig. kn
When coal burns it leaves ash behind. Ash so produced is lighter than the coal which has burnt. Justify the decrease in mass in the light of law of conservation of mass.?
During combustion carbon dioxide and water are released; ash is only the residue.
The first stage in the information of coal is?
Rotting vegetation is overlaid by more rotting vegetation or other material. This is compressed by the mass above and form peat. Compression of the peat continues and form lignite (brown coal) Compression continues on the lignite to form coal (clack shiny rock) Compression may continue to form anthracite , the hardest form of coal . NB with each compression watert/moisture is expelled, so coal and anthracite are very dry.
What is a coal holder called?
Coal Bunker, Coal scuttle, Coal hod

Is a coal's mass measured in milligrams?
A milligram is a very small amount (a teaspoon is 5 mg of water). So not a unit to weigh coal in.
What made the transition from one a a time manufacturing to mass production possible?
coal
How much does a of cubic meter of coal weight?
First find the bulk density of coal as per the respective grade. then multiply density with volume you will get mass

During combustion carbon dioxide and water are released; ash is only the residue.
What has the author Constantine Tsonopoulos written?
Constantine Tsonopoulos has written: 'Thermodynamic and transport properties of coal liquids' -- subject(s): Coal liquefaction, Mass transfer, Thermodynamics
How are volcanoes different from coal?
coal is a mineral found in the earth where as a volcano is a large 'tunnel like' land mass leading deep within the earth it is similar to a pipe but for lava.
What were the innovations of the industrial revolution?
the use of coal powered machinery and mass producing by machine, not hand made.
The first step in surface coal mining is?
It's the material added to land to form land mass.

What is the equivalent mass of uranium which produces same energy equal to one metric ton of coal?
7 g 235U is approx. equivalent to 20 t coal (for the complete fission of the uranium). For 1 t of coal - 0,35 g of 235U !
