1. ### Climate Sensitivity math problem

Would I put this into a ratio? If so how would I set this up?
2. ### Climate Sensitivity math problem

How would I go about finding this then?
3. ### Climate Sensitivity math problem

So I would use the maximum amount to find the ration? This would be .12K right? How would I then use the .9 C. This is also in Celsius so would I need to convert?
4. ### Methane and CO2 atmospheric lifetime math problem

Homework Statement On a per-molecule basis, methane is 26 times more effective as an infrared absorber than is CO2. Calculate the corresponding ratio on a per-unit-mass basis, and compare it with the 20-year GWP for methane. What's the reason for any discrepncy you find? (CO2 atmospheric...
5. ### Climate Sensitivity math problem

Would I do .06 W/m^2 x .5K =.03K and .24 W/m^2 x .5K= .12 K and then do .03K/.12 K= .25K or 25%?
6. ### Climate Sensitivity math problem

What do you mean by the right units? And how would I find this as a percentage?
7. ### Climate Sensitivity math problem

So for the maximum forcing would I do .5K x .24 W/m^2? Is there more to this problem though?
8. ### Climate Sensitivity math problem

So would this mean I would do .5K x .06W/m^2 ?
9. ### Climate Sensitivity math problem

The minimum value for solar forcing would be .06 right? But how would I know the temperature difference?
10. ### Climate Sensitivity math problem

Homework Statement Using a climate sensitivity of 0.5K per watt per square meter, estimate how much of the .9 c global temperature increase since 1900 could be due to solar forcing who value is the range of .06 to .24 w/m2 Homework Equations The Attempt at a Solution I am not...
11. ### Energy content of gasoline and hydrogen comparative math question

I don't understand what this means though? Is this all the information I need?
12. ### Energy content of gasoline and hydrogen comparative math question

Wait I realized that is only for 1 gallon so I got 28530 MJ
13. ### Energy content of gasoline and hydrogen comparative math question

When I did this I got 1902.214 MJ. Is this right? If so how would I go about doing part B?
14. ### Energy content of gasoline and hydrogen comparative math question

When I did this as a ratio I got 133,155 g of CO2 but thats still not the answer in the back of the book is there another step?
15. ### Energy content of gasoline and hydrogen comparative math question

Would I just divide these two?
16. ### Energy content of gasoline and hydrogen comparative math question

So 1 gallon of gasoline contains 36,315 g of Carbon which will produce 70 g of CO2 but then what?
17. ### Energy content of gasoline and hydrogen comparative math question

In the oranges case I would multiply 20 by .30 So for this would I multiply 44 x 70 x36,315?
18. ### Energy content of gasoline and hydrogen comparative math question

How would I set this up as a ratio?
19. ### Energy content of gasoline and hydrogen comparative math question

The answer in the back of the book is 2.2 billion J but I don't know how this was gotten. I don't know what to do with the above info
20. ### Energy content of gasoline and hydrogen comparative math question

So if the atomic mass of carbon is 12 and the atomic mass of oxygen is 16 what do I do with this? Also I have two oxygen so would I add all of these to get 44? The answer in the back of the book for part A is 2.2 billion J but I have no idea how this was gotten.
21. ### Mars and Jupiter's atmosphere math question

Homework Statement What should be the temperature of a spherical asteroid located between Mars and Jupiter, twice as far from the Sun as Earth? The asteroid has no atmosphere and its albedo is .15. Homework Equations The Attempt at a Solution The asteroid is twice as far from...
22. ### Energy content of gasoline and hydrogen comparative math question

I am not sure how to connect the two? Do I already have this info?
23. ### Energy content of gasoline and hydrogen comparative math question

I know that gasoline produces 70 g of CO2 - not sure if this is relevant though?
24. ### Energy content of gasoline and hydrogen comparative math question

I know that produces 70g of CO2. Would I use this?
25. ### Energy content of gasoline and hydrogen comparative math question

I am not sure what you are saying? Is part A correct or do I need to do more to solve the problem?

grams
27. ### Energy content of gasoline and hydrogen comparative math question

So if carbon content per gallon of gasoline is 2421, would I then do 15 gallons x 2421 grams to get 36,315 g? How would I go about solving part B?
28. ### Energy content of gasoline and hydrogen comparative math question

Homework Statement A typical car gas tank holds 15 gallons A) Calculate the energy content of this much gasoline B) Calculate the chemical energy content of 15 gallons of hydrogen gas under normal conditions (12.8 MJ/m^3) and compare with the energy content of gasoline Homework...
29. ### Waste power plant efficiency math problem

Also the energy density is 20 MJ/kg not sure what this means though
30. ### Waste power plant efficiency math problem

Homework Statement If 230 million tonnes of solid waste were burned in waste-to-energy power plants that are 20% efficient a) how many kilowatt- hours of electrical energy could be produced in a year? Compare this quantity with the total US electrical energy production of 3.8 trillion...
