Why is petroleum jelly used in hanging drop method?
This type of sealing material is used primarily to reduce evaporation of liquid and to eliminate air current in the preparation.

What changes take place to the air as it enters through your nose?
as air enters through the nose the minute dust particles stick to the hair inside the nose. then air enters the wind pipe . as it travels down the wind pipe the oxygen present is absorbed by the lungs which in turn sends the purified air to the heart. the impure air or the co2 is sent back.
What is the range of beta particles in the air?
The range of beta particles in the air is up to several hundred feet. Beta particles are emitted by specific types of radioactive nuclei. Potassium-40 is a type of radioactive nuclei that emits beta particles.
Particles of carbon what enters the air when wood and coal are burned are called?
Carbon monoxides are particles of carbon which enters the air when coal and wood are burned.
Why is petroleum jelly used in the hanging-drop procedure?
Petroleum jelly is used in the hang drop procedure because , it reduces the evaporation of the drops of fuild . ---------------------- ALSO, this type of sealing material is used primarily to not only reduce evaporation of liquid but to eliminate air current in the preparation as well.

How do you clean and soften windshield wiper blades?
You can clean them by wiping them off with a vinegar-soaked cloth. It's not worth taking the time to soften them--they're cheap enough you can afford to just pull them off, throw them away and get new ones. You can soften them by applying petroleum jelly after you have cleaned them. Don't wipe off the petroleum jelly. Let it them air dry for about 10 minutes. Clean them first by using a soft cloth wet with vinegar & them wipe them a with a water dampened cloth. Wipe dry & then apply the petroleum jelly.
When was Petroleum Air Services created?
Petroleum Air Services was created in 1982.
What process takes place when water vapor molecules in the atmosphere stick to particles in the air and becomes a liquid?
"condensation"
Can plants manufactured food properly if their leaves are covered with petroleum jelly?
No - this would probably kill the plant. First, the jelly would likely refract the light, significantly reducing the amount of energy available for photosynthesis. Second, the jelly would block the stoma through which carbon dioxide is absorbed from the air for use in photosynthesis.
Why is petroleum bad?
petroleum is a major issue in air pollution.
Leaves of healthy potted plants were coated with vaseline to block the stomata will this plant remain healthy for long state two reason for your answer?
· No not at all the plant will die. 1. stomata will be blocked as petroleum jelly will not let the air to pass through and will make the stomata unable to respire. 2. The petroleum jelly absorbs heat and vaseline is a petroleum jelly. this will adversely affect the plant and will harm its leaves and stomata's. 3. The chemical composition of Vaseline contains the residue and compounds of petrol and its product which is very harm full for the plants and these composition can dry up a potted plant if applied on their leaves.
Why transparent glass of windows if not wiped off ragularly appears hazy?
1. The air contains dust particles along with other gases. These dust particles stick to the window and make it appear hazy. 2. Air contains water vapour. So when the air containing water vapour gets in contact with the window, the water creates stains on the window and make it appear hazy. Thus transparent windows should be wiped regularly.
What are the positive uses of static electricity?
Some people purchase what are called air ionizers to freshen and purify the air in their homes. They work on a similar principle as the smokestack pollution control. These devices strip electrons from smoke molecules, dust particles, and pollen in the air, just as what happens in creating static electricity. These charged dust and smoke particles are then attracted to and stick to a plate on the device with the opposite charge. After a while, much of the pollution is drawn from the air. Since charged particles will also stick to neutral surfaces, some of them can stick to the wall near the ionizer, making it very dirty and difficult to clean.
What does air move from?
air moves from particles to particles
What particles does air-contain?
Air particles contain oxygen.
