When we blow air onto to the mirror the image in the mirror was not clear?
It became foggy with moisture from your breath.
How does bubble form?
Can you blow a bubble with pure water? NO WAY... because the surface tension of the water does not allow you to do so.Can you blow a bubble with soap-water solution? YES...Soap molecules contain hydrophobic chains that do not wish to stay in water. so they squeeze out to the surface of water and increases the gap between the water molecules on the surface, there by decreasing the surface tension of the water. With surface tension decreased you can blow a bubble.Here you can ask one more question...Why are Bubbles always spherical and not cuboid or some other shape?
Why does moist form on the suface of the mirror after you blow on it?
The mirror get "moisturized" when you blow on it since your breath has water vapors in it. Once you breathe or blow onto the mirror, the water vapors from your mouth go onto the mirror and cool down, causing it to look like a cloudy surface.
What happens to the speed and pressure of a fluid when the space through which it flows becomes narrow?
first it causes u to fat and the u blow up
Does America have enough nuclear weapons to destroy the world?
To destroy the planet (as in blow it into pieces), no. But to destroy all live on the surface, yes.

What is the blow past in engine?
Blow by or blow past is leakage of combustion gas between ring and liner surface. It may happe due to wear of liner surface. Causes for it: lubrication fail, suffing, older engine etc.
Why does a volcaneo erupt?
A volcano erupts when magma below the surface becomes presured and makes its way up the volcano until it can't go any further and sits and builds pressure until it blow with extreme power
What does detergent do to the surface tension of water?
It weakens the surface tension of water allowing us to blow BUBBLES!! :D

Why do surface winds blow on a curved path?
Because the Earth rotates.
What happens to the amplitude of a wave as strong winds blow it over the ocean's surface?
The amplitude is increased by strong surface winds.
What happens when you blow a straw into lime water?
It becomes milky, indicating the presence of Carbondioxide.
Earth's surface winds generally blow from regions of higher..?
air pressure
What happens when the winds in the tropics blow warm surface water out to sea?
hurricane
How a bottom blow down valve differ from a surface blow down valve?
their difference is very simple. surface blowdown valve is for light impurities while bottom blowdown valve is for heavy impurities such as sludge, etc.
Distinguish between surface winds and upper atmosphere winds?
Surface winds blow along the surface of the earth.Sometimes they blow in the same direction all year around .Sometimes they blow mainly in one direction for other part of the year.For e.g the monsoons in the sub-continent. In other places the winds are likely to blow in different direction from day to day.Winds speeds can vary from very slow to 100 km pr/hr. Upper atmosphere winds blow at about 10,000 meters above the surface of the earth. They are caused by the rotation of the earth and blow steadily in the same direction all year round.They can reach up to speed 350 km to 450 km/hr.They are referred to as the jet stream.
