Place the following energy states in order of their least net carbon dixide emission into the atmosphere, where 1. = lowest net carbon, and 5. = highest net carbon. In your calculation, take into account: How much carbon dioxide (or CO2 equivalent) is emitted per unit energy generated. If the source is renewable, how much carbon dixide (or CO2 equivalent) is removed from the atmosphere each year by that resource. How much energy is needed to produce and deliver that energy source. - Oils. Petroleum fractions, plant oils, and similar viscous substances, ccommonly combined with lighter distillates to form diesel fuels for truck and rail engines. - Gaseous. Hydrocarbons, hydrogen and carbon monoxide mixtures present in gaseous state at room temperatures which, when combined with oxygen (burned) release heat and/or light. - Solid fuels. Fossil carbonates (coals and peat), carbonized woody materials (coke, charcoals, and biochars), and lignite (woody) fuels including wood, pelletized grasses, etc. burned directly in their solid state.

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.
