Does atmospheric pressure affect tornadoes?
Yes. Tornadoes themselves are small, intense centers of low pressure.
Why are aromatic water be prepared in small amount and be protected from intense light?
The scope is to avoid rapid degradation.
Why corrosion occurs under a rivet?
It is known as dissimilar metals corrosion. Whichever metal is softer will tend to corrode more quickly than the harder metal. All metals corrode because nature is trying to return the metal to it's natural state. As the slave metal corrodes it actually produces some electricity. In fact that is exactly how a battery works. The reaction of the cathode to the anode causes a measured amount of electical activity. Also, on ships the paint they use has small metal particles in it to draw the corrosion to themselves rather than the ships hull. Everything is always trying to return to its lowest origin and corrosion is the way metal does it.
When testing microaerophils some microbiologists prefer to use a semisolid nitrate medium that contains a small amount of agar why is this done?
Microbiologists testing microaerophils prefer to use a semisolid nitrate medium that contains a small amount of agar to get more accurate results. This is also done to speed up the results.
What is steel corrosion resistance?
whichever substance that neutralises or reacts with chromic oxide will corrode stainless steel. search for chemical properties of chromic oxide. stainless steel is considered as a "corrosion resistant alloy" that means that is more resistant than the common steel to corrosion. a typical corrosion reaction is when stainless steel is incontact with fluid that contains chlorides, like seawater, and small pit are produced.
What can accelerate corrosion reactions?
Anodic current; temperature; acid; repeated stress (stress corrosion cracking); water; salts especially chlorides; a dissimilar metal placed in direct contact (galvanic corrosion). Poor painting (pinhole corrosion - concentrates all the anodic current in one small place) and others
Write differences between Anodic Coatings and cathodic coatings?
In anodic system, small amounts of the metal migrates into the coating film limiting it's usefulness in corrosion protection. Anodic coatings are used in less severe environments and are generally economical and produce a nice surface finish. Cathodic systems produce an coating free of metal migration and are much more robust. These systems are useful in heavy corrosive environments.
What structure enables the small intense to absorb large amounts of?
the large intense
When you turn the key to start your car it turns without starting?
dead battery or corrosion on eletrical connections wet wireing in motor bay if no response corrosion may be problem even if only small amount of corrosion can abstruct normal eletrical functions
What is pitting in engineering?
Pitting is when there are small holes starting to appear in steel often caused by corrosion/rust
What could cause a small c battery to explode?
They will not explode. It may expand and burst due to corrosion.
What sends a narrow intense beam of light?
a small laser, or a laser pointer
Why would small transformer suddenly stop working and then start again at a later date?
Check for a spot of corrosion!
Was Cyclone Tracy a typical cyclone?
No. Cyclone Tracy was an a very intense but abnormally small cyclone.
Bigger the hurricane the more intense?
Not necessarily. Hurricane Charley in 2004 was relatively small but was a category 4.
Does atmospheric pressure affect tornadoes?
Yes. Tornadoes themselves are small, intense centers of low pressure.
Why are aromatic water be prepared in small amount and be protected from intense light?
The scope is to avoid rapid degradation.
