Low energy coal, because it has been compressed the least amount of time.
What is Lignite
100
Measurement of heat energy
What is temperature
100
Carbon is able to bond with atoms of other elements in many different ways because it has this many
What is 4 electrons
100
The process of combustion to release heat or thermal energy also produces this molecule at a product.
What is CO2
100
This is a solution to CO2 and pollutant emmissions of internal combustion engines. Most commonly involves a catalytic converter
What is ERG or Emmission Gas Recyclers
200
Heat that comes from the earth's core that processes organic material into oil and gas
What is geothermal heat
200
Unit of energy that equats the amount of heat needed to raise the temperature of 1 gram of water by 1 degree celsius
What is calorie
200
This is what you can tell by looking at the molecular formula of methane gas. CH4
What is one carbon and four hydrogens
200
This forms when CO2 and other pollutants of combustion combine with rain
What is acid rain
200
This is a problem of the CO2 cycle when green house gases grow and ozone levels are destoyed.
What is global warming
300
loose brown organically rich soil that becomes compressed by rock
What is peat
300
Device that measures the calories of substances by heating water
What is a calorimeter
300
Compounds that contain only the elements carbon and hydrogen are called this
What is hydrocarbon
300
The cycle of CO2 that involves respiration and photosynthesis
What is natural CO2 cycle
300
This is a solution to CO2 emmisions that involves creating an electric feild inside smokestacks to collect pollutants
What is electrostatic precipitators
400
carbonaceous rock formed from ancient forests and swamps
What is coal
400
The number of calories released when one gram of a compound burns
What is heat content
400
Fossil Fuels are energy rich because they contain this chemical structure
What is hydrocarbons or Hydrogen and carbon bonding
400
This is the cycle that produces CO2 in our atmosphere due to the combustion of fossil fuels
What is unnatural
400
This is a problem of the CO2 cycle that involves air pollution and sometimes death
What is smog and CO
500
Liquid form of fossil fuels that can be converted into many energy sources
What is petroleum
500
1 calorie/gram of water
What is the specific heat of water
500
This hydrocarbon fuel source produces the most pollutants when burned because it contains mostly carbon and other elements such as sulfur and nitrogen.
What is Coal
500
When 1 molecule of methane in burned what these are the products of the balanced chemical equation
What is CO2 + 2H20
500
This is a solution to the CO2 emmissions problem that coal plants used to filter out pollutants with in the smokestacks. It usually involves a limestone water bath.
