Question about science?

Question

Hi, I got some question about science. Can your guys help me?Thanks

1. When radiation fog occurs, people often say that the fog will"burn of" later in the morning or afternoon. You know that water can't burn, so what does it mean to have the fog"burn off"?(where does the fog go?)

2.Who do the windows inside a car" fog up
when several people are riding in it on a cold day? how does a " defroster" work to get rid of the "fog"? (What does a defroster produce?)

3.why doe radiation fog only in the low lying areas(think about desnity and what is needed to form a cloud.)

4.What has caused the "hole" in the ozone layer?

5.Where is the "hole" located?

6.How is the"hole" measured and located?

7.Can anything be done to fix the"hole"?

8.How are the people who live under the "hole" affected?

Answer 1

#1 It evaporates. #2 This is condensation #3 Different density. #4 Some say man, but nature affects it also. #5 Antarctica #6 The "so called hole" changes size thru out the year (increases and decreases), like I said above natural occurances affect this also. #8 No one lives under it. ~A~

Answer 2

1. The term "burn off" is not a scientific term, it just means the fog goes away when the day warms some.

You are right, water will not burn, it just evaporates when the air gets dryer.

2. People exhale warm moist air (because people are warm and water is one of the by-products of metabolism). When warm moist air is cooled, the water condenses. A cold glass will condense the moisture in the air and "fog".

3. Fog is often denser than the air above and around it and so it sinks into low areas. It is formed in the "cooler" air and cooler air is more dense than warmer air.

4. No one knows for sure what caused the "hole" in the ozone layer. Since we have been able to measure it, there has always been some hole. The whole has gotten bigger in recent years. The top theory for the reason for the increase in the size of the whole is that certain man-made pollutants (such as come fluoro-carbons) rise in the atomosphere and eventually react with ozone to deplete the ozone layer.

5. The large ozone hole is located above the south pole.

6. I don't know precisely how they measure the ozone layer. I believe at least one technique involves weather balloons sent to bery high altitudes.

7. Nobody knows for sure. Some theories indicate that reducing certain man made pollutants will let the hole fix itself.

8. Nobody lives under the "hole".

Answer 3

1. They just mean it will fade off. The fog condenses back into water.
2. Their warm breath and such condense on the colder window. Sorry, I don't know anything about defrosters.
3. I'm guessing by 'radiation fog' you just mean fog, so yes, it is because it is of higher density than clear water vapor and will therefore go to lower places.
4. Chemicals in human-made junk like hair spray.
5. It's not one hole.
6. Satellites, radar, etc.
7. Stop using chemicals that destroy it.
8. More radiation, more prone to skin cancer.
