P1V1/T1=P2V2/T2 P2=1/2 P1 V1=1 T1=298K
1 P1/298= (1/2) P1V2/373 cross P1
1/298=1/2V2/373
1/298=1/V2 746
v2=746/298
V2=2.5L
(D) Mass and energy can convert to one another.
Natural sources include decomposition,ocean release and respiration.
Human sources come from activities like cement production, deforestation as well as the burning of fossil fuels like coal,oil and natural gas.
