What is galvanic series?
Each metal when placed into an electrolyte, water, seawater, soil or any other good electrolyte, has an electric potential. This potential is different for every metal. The galvanic series is a list of this potential arranged from the most "active",lower potential to the most "noble", higher potential. The terms "noble" and "active" means that when two metal are connected the most "active", with the lower potential will corrode, while the metal with the higher potential, the "noble" material will not corrode. The galvanic series, the potentials, are different in different electrolyte.
What effect will a positively charged metal plate have on a cathode ray?
Since a cathode ray is a stream of electrons, and since electrons are negatively charged, a positively charged metal plate would cause a deflection in the cathode ray towards the plate.
What is the purpose of Standing Seam Metal Roof?
Standing seam metal roofs offer a better cooling effect than regular shingles. They are typically long panels which run from the top of the roof to the eaves. The seams are raised, protecting the underlay from leaks.
How does torsion effect a bridge?
There are 3 ways to prevent rusting A. Plate the metal with another metal, expensive. B. Paint or coat the metal with a chemical that prevents the metal from getting wet. C. Chemically treat the metal so it can only rust a little and it cannot rust through. Depending on what you are working with would determines the method you use.
What is magnetic arc blow?
Most stick welding SMAW is done with Direct Current DC. As this current passes thru the base metal it can set up a circular current on either side of the weld area creating a magnetic effect. The arc is affected by this and whips back and forth drawn by this magnetic field. Metal is blown out of the arc and splatters onto the sides of the weld and the arc is hard to control. This arc blow can be reduced by passing a separate magnetic field thru the metal nullifying the effect, or by welding in the opposite direction, or by using Alternating Current AC
What is a light metal extracted from seawater and used in the aircraft industry?
aluminium
How is magnesium obtained from seawater?
When fresh water is removed from ocean water, the salts that are left behind are also a valuable resource. Over half of the world's supply of magnesium, a strong, light metal, is obtained from seawater in this way.
When the mineral-rich water from a hydrothermal vent hits the surrounding seawater the minerals rushing out give the water the appearance of?
"black smoker" due to the dark color caused by the precipitated minerals like sulfide compounds and metal sulfides. The minerals are released from the hot vent fluids mixing with the cold seawater, creating a distinct visual effect resembling smoke.
What has the author John Sinclair Locke written?
John Sinclair Locke has written: 'Investigation into the effect of dissimilar metal coupling, potential, and processing on the mode and distribution of galvanic corrosion attack on 5086 aluminum alloy in synthetic seawater' -- subject(s): Mechanical engineering
Can you take sea water and drink it?
On average, seawater in the world's oceans has a salinity of about 3.5%. This means that every kilogram, or every litre, of seawater has approximately 35 grams (1.2 oz) of dissolved salts.Accidentally consuming small quantities of clean seawater is not harmful, especially if the seawater is consumed along with a larger quantity of fresh water. However, drinking seawater to maintain hydration is counterproductive; more water must be excreted to eliminate the salt (via urine) than the amount of water that is gained from drinking the seawater itself. The effect of seawater intake has also been studied in laboratory settings in rats.This study confirmed the negative effects of drinking seawater when dehydrated.
Which process does not add salts to seawater?
Storms at sea. The evaporated water falls back into the ocean with no net effect on salinity.
What effect does sprite have on metal?
it disintegrates
What is the side effect of metal detectors?
The side effect of metal detectors is that it prevents the use of weapons and it also prevents violent crimes. The side effect of metal detectors is that it prevents the use of weapons and it also prevents violent crimes.
Effect of fertilizer application on metal load in Oil palm plantation?

Is a Seawater a mineral?
Seawater is water with salt in it
In the photoelectric effect what happens when lighthits the metal?
When light hits a metal in the photoelectric effect, it can transfer its energy to the electrons in the metal. If the energy of the light is high enough, it can cause the electrons to be ejected from the metal, creating a flow of electrical current.
What are 2 main factors that influence density if seawater?
Temperature and salinity are the two main factors that influence the density of seawater. Colder seawater is denser than warmer seawater, while seawater with higher salinity is denser than seawater with lower salinity.
