Answer:
chloroplast photosynthesis
Explanation:
Photosynthesis is the process by which green plants create their own food by turning light energy into chemical energy. ... Cellular respiration, on the other hand, is the process by which living things convert oxygen and glucose to carbon dioxide and water, thereby yielding energy.
Answer:
democritus is the first person
First convert the 2 temperatures to degrees K:
4 + 273 ---> 277 and 22---> 295
So using Charles' Law
V1 / T1 = V2 / T2
0.50 / 295 = V2 / 277
solving for V2 gives a volume of 0.469 L to nearest milliliter
Answer:
coal
Peat
Bituminous
Anthracite
Explanation:
Peat is the first step in coal formation. Peat is composed of over 60% organic matter; typically, ferns and vegetation found in swamps or bogs. As a result of the high water content of this environment, peat contains a lot of water, which limits its heat content or the amount of energy it contains. It's a very soft brown coal.
Bituminous coal is formed as more pressure is applied to lignite coal. The greater the pressure applied, the more water is expelled, which increases the amount of pure carbon present and increases the heat content of the coal. Bituminous coal is often classified as sub-bituminous or bituminous. The difference is that sub-bituminous is the transition stage from lignite to bituminous coal. Bituminous coal is widely used in the United States and across Europe.
Anthracite coal is a metamorphic rock and is considered the highest grade coal. It's hard and dark black in color. It has a very light weight when compared to other forms of coal, as there is very little water present in anthracite. As a result, anthracite has the highest heat content. Anthracite is formed when bituminous coal is subjected to great pressures, such as those associated with the folding of rock during the creation of mountain ranges.
coal is just well...coal :3
