PLEASSSEEE HELP The energy density of compressed natural gas (CNG) held at 3600 psi pressure (about 245x atmospheric pressure) is 2500 kWh/L. Compare the energy density of methane (natural gas is ~ 94% methane) you estimated in the table above to the energy density of CNG at 3600 psi. Explain why the two values are different (you will have to do some unit conversions to answer this question).

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.

explanation:

the answer is b. dilution

i believe the answer is true.

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
