Science FAQ
Why Does Latent Heat Of Melting Take More Energy Than Latent Heat...
It doesn't. The latent heat of vaporisation is higher than the sleeping heat of fusion (melting), because the energy required for the phase change from solid to gooey is less than that required to jump from liquid to the much more overexcited...
Why Does Lead Have The Symbol Pb?
Lead is a soft, corrosion resistant greyish metal that is found commonly in air, river, food and paint. Lead is chemically symbolized as Pb which is an abbreviation of the Latin name plumbum. Incidentally, the English word "plumbing" is also originated from equal Latin root. The relationship between...
Why Does Life All Depend On Water?
Because most living things are made up of some % water so we need that water contained by our systems to survive, and to replenish what we lose Plants use water to release some of there nutrients.
Why Does Lightening Kill?
Lightning kills when it goes through the body and interrupts the hearts rhythm. If the current is high-ranking enough it can damage some or all the organs contained by the body and cause them to die. Once the heart is stopped unless another electrical pulse is given the heart will not restart. That is...
Why Does Lightning Flash Before You Hear The Thunder? Explain
Because the speed of light is much faster than the speed of sound. Because light travels faster than nouns.
Why Does Lightning Hit Things?
Conductors attract it. Lighting is attracted to heat anything that moves at a fast pace that make heat or gives off heat it'll strike it.
Why does lightning other come earlier thunder?
During a storm, there is a discrepancy between areas of air between regions of warm and cold. This cause frictional forces to build up, which sometimes creates an electrical spark. This is lightning. At the same time, sound energy is produced by the friction between the different...
Why does lightning take place?
Lightning occurs more frequently during the summer months, because you need warm, moist nouns to create the right conditions. What is known is that raindrops are forced up into the cloud until some turn into ice ~ this normally happen around 20,000ft above sea level. There is some disagreement about...
Why does lime liquid craft pennies turn green?
It probably has something to do with the acidity of the lime liquid some how effecting the charge of the copper ions. Definatly from The acids in the Lime Juice.
Why Does Liquid Have A Definite Volume But Gas Does Not?
Thessa Liquids are not compressible. Gases are compressible according to the equation pv=c, this is also called Boyles law. Liquids do not obey Boyles imperative and are therefore not compressible. Therefore liquids have a fixed volume. I will refer you to Boyle's statute. Gases...
Why does magnesium form alkyl magnesium halide? And why aluminum does...
In Mg there are two electrons available for the bonding one of which makes bond with alkyl group and other next to the halides to form alkyl magnesium halides.
Why does magnesium metal come between halogen and alkyl group?
Each alkyl group and halides require one electron to complete their outer most shells and magnesium requires losing two electrons to become neutralize. So it gives one electron to alkyl group and other to halide group.
Why Does Manager Have To Study The Managerial Economies?
Managers and business students are taught Managerial economics because it includes various concepts and strategies which will help them within their decision making. Managerial economics enable managers to enrol techniques such as net present value for investing verdict, game theory to take prerequisite price actions to...
Why Does Metal Have A High Melting Point??
Well i need to know In metals atoms are bonded together very firmly,in which a positive ion can be imagined to be immersed n a the deep of electrons,and the positive ion attracts all electrons within its sphere of influence.This is called as mettalic bond.To break...
Why Does Methane Have Exactly Four C-H Bonds?
Carbon needs 4 electrons to make its valence shell stable..............these 4 electrons are shared by the four hydrogen atoms...........each hydrogen atom wants 1 electron to become stable and carbon having four of its own electrons need 4 more that are shared by the hydrogen atoms
Why Does Mixture Fizz And Cause Its Reaction?
Need more details, which mixture?? I can guess NaHCO3, Bicarb and acetic acid. The fiz is gas given off, CO2 I believe. Re-ask if you have more info.
Why Does Mold Grow In Dark, Moist Places?
I'm doing a project on mold in Biology and I can't find ANYWHERE exactly why it is that mold prefers to grow in dark and moist places. Somebody PLEASE HELP! Different types of mold can grow contained by different ways. They have tiny spores which can...
Why Does Mold Only Grow In Hot Weather Rather Then Cold Weather?
We are in a condo in FL that is individual renovated and the walls will be torn out in Aug. With no air conditioning for about 3 weeks. Will mold potential form on upholstered furniture....or how can the furniture be protected? Mold only grows...
Why Does Molten Sodium Chloridde Conduct Electricity But Solid Sodium...
Sodium chloride is ionic. When it is molten, it undergoes electrolysis. Electricity is conducted by the movement of the ions that are discharged at the electrodes. When sodium chloride is in solid form, the ions are tied up and are not free to move,...
Why Does Most Of The Helium Filled Ballons Burst As It Ascend To High...
I need to know the answer for our project in school. The defence would be that when helium filled balloons are released they ascend to high altitudes. At glorious altitude the external atmospheric pressure decreases so the strong difference...
