| ALTHOUGH CFCS NO LONGER PRODUCED SOME STILL IN.... | THE UPPER ATMOSPHERE BRUH.
🗑
|
||||
| HCFCS ARE PRODUCED AS .... | REFRIGERANTS AND CAN ESCAPE.
🗑
|
||||
| CO2 FORM FOSSIL FUELS COMBUSTION HAS ... | HIGHEST PROPORTIONS OF GREENHOUSE GASSES EMISSIONS.
🗑
|
||||
| WHEN REFERING TO GREENHOUSE GAS YOU HAVE TO CONSIDER THE... | EFFECTIVENESS IN ABSORBING INFRARED RADIATION AND THE TIME THE GAS SPENDS IN THE ATMOSPHERE BEFORE BEING REACTED OR DEPOSITED ON THE EARTH’S SURFACE.
🗑
|
||||
| METHANE ABSORBS MORE RADIATION PER MOLE THAN... | C02.
🗑
|
||||
| OXIDES OF NITROGEN AND HCFCS ARE MORE... | POWERFUL ABSORBERS.
🗑
|
||||
| GLOBAL WARMING POTENTIAL (GWP)... | OF EACH GAS.
🗑
|
||||
| (GWP) IS BASED ON THE ABILITY.... | THE GAS HAS TO ABSORBED INFRARED AND THE EXTENT TO WHICH IT CAN BE REMOVED.
🗑
|
||||
| C02 IS USED AS STANDARD AND GIVEN GWP RATING... | OF 1.
🗑
|
||||
| GWP OF METHANE... | = 20, NO = 300.
🗑
|
||||
| IF THE GLOBAL WARMING POTENTIAL AND CONCENTRATIONS OF GASES ARE KNOWN.... | THE EFFECT OF THE ENVIRONMENT CAN BE CALCULATED.
🗑
|
||||
| THE TOTAL C02 EMISSIONS ACCOUNT FOR WHAT %... | 84% OF THE GREENHOUSE GAS EMMMISIONS, BUT THE EFFECT OF C02 IS ONLY 50% COZ OF THE LOWER GWP.
🗑
|

| WATER VAPOUR ACCOUNTS TO WHAT %... | 95% OF THE TOTAL GREENHOUSE EFFECT.
🗑
|
||||
| ONLY 3% OF THE C02 IN THE ATM IS ... | OF ANTHROPOGENIC ORIGIN. CO2 CONTRIBUTES JUST 0.1% TO THE TOTAL GREENHOUSE EFFECT.
🗑
|
||||
| CONTRIBUTION OF GREENHOUSE AFFECT (%) ... | WATER VAPOUR: 94.6 ,CO2 – 3.8, METHANE=1.1,NO =0.5 , OTHERS <0.1.
🗑
|
||||
| INFRARED SPECTROSCOPY IS THE... | MEASURE THE AMOUNTS OF RADIATION ABSORBED , THOSE THIS BY SPLITTING THE INCIDENT BEAM INTO 2.ONE BEAM PASSED THROUGH A CELL CONTAIN A REFERENCE SAMPLE (USUALLY SOLVENT) AND
🗑
|
||||
| THEN GOES TO THE DETECTOR; |
🗑
|
||||
| IN INFRARED SPEC THE OTHER GOES ... | THROUGH THE DISSOLVED SAMPLE TO THE DETECTOR. THE DIFF BETWEEN THE 2 AMOUNTS OF RADIATION ARRIVING AT THE DETECTOR IS THE AMOUNT ABSORBED BY THE CHEMICAL.
🗑
|
||||
| THE ANGLE OF DIFFRACTION GRATING IS SLOWLY ALTERED IN INFRED SPEC WHY.... | SO THAT THE DIFF FREQUENCIES SWEEP THROUGH THE APPARATUS.
🗑
