Why do certain types of coal give off more carbon dioxide than other types of coal?

Coal is not all the same. Different coals have different amounts of carbon, Bituminous, or soft coals have the highest percentage of carbon, up to almost 90%, Anthracite or hard coals have close to 80% carbon content, and lignite, brown coals have about 40% carbon content. Carbon content is what determines how much CO2 is produced by coal's combustion.


What are the four major types of air masses according to moisture content?

Precipitation


What instruments measure air moisture?

A hygrometer measures the moisture content of the air. There are several different types, all of which measure something else which indicates the moisture content.


As coal forms how does its carbon content change?

It compacts and increases as moisture and volatile hydrocarbons are driven off. Coal has a carbon content between 75 and 90 % , lignite (brown coal) hasn't completed the transformation and contains more moisture and nitrogen than bituminous or anthracite coals. Lignite has about 30 to 40% carbon content.


What is the proper refraction for honey?

Honey refraction is a measure of moisture content. Generally, the best moisture content is 17-18%. Higher that 21% usually is unfit to sell. However, since different types of honey have different specifications, you might be able to accept a moisture content of 23% for clover honey. See related links to read about various refraction and moisture content information.


Why you are doing initial moisture content critical moisture content and equilibrium moisture content test?

if we know initial moisture content of the object we can identify how much drying energy required for dry the same moist material. if it is a food material we have to reduce the moisture content upto certain level, otherwise it may be destroyed. if we know the initial moisture content of same food object, we can reduce its moisture content upto 10% of its initial moisture content.


Are plants a renewable resource?

Yes, plants are renewable in the right soil types, moisture content, and temperatures.


Maximum bulking in sand and in what moisture content?

Why is it that materials with moisture content has high k values?

Discuss why materials with moisture content have high k-values


What is the moisture content of fruit powder?

The moisture content in fruit powder should be zero. Any moisture will cause the powder to cling together, and encourage the growth of mould.


How does a moisture meter give a reading of the moisture content of wood?

By passing an electrical current from one pin to the other. The greater the moisture content, the higher the resistance. By measuring the resistance, it gives an estimate of the average moisture content. I think. 2009/03/14 - Correct, but exactly backwards .... Moisture (water) can be a conductor. Dry wood is an insulator. The higher the moisture content, the lower the resistance and vice-versa. Wood with a high moisture content gives a low resistance to the tester and conducts the test voltage better.


What is the cleanest type of coal to burn?

Anthracite can be the cleanest of coals if it has a low ash and sulfur content.
