At what stage of reaction do atoms have the highest energy?
The transition stage is the stage of a reaction where atoms have the highest energy. A covalent bond forms when atoms share electrons.
How do scuba divers sink if they have tanks of compressed air on their backs?
The average aluminum SCUBA cylinder holds 80 cubic feet of air at pressure. That means you are taking the equivalent of a closet's worth of air and smashing it into a cylinder much smaller than that. When full, the cylinder is at 3,000 pounds per square inch of pressure.When the valve is opened, it sends air into the (assumed) first stage regulator which is connected by hoses to gear such as two second stage regulators, instruments and your vest.So the SCUBA tanks don't so much USE the air so much as STORE the air at high pressures.
What is the highest galaga score in the world?
my highest score is 484,200 if anyone has scored more than that id like to know,i got to stage 40
How does a three stage compressor work?
There are several kinds of compressors--reciprocating, screw, centrifugal. We'll use a reciprocating compressor in this example. It's got a piston moving back and forth in a cylinder to compress the air. (It's like a car engine, and you can get a kit to turn an old Volkswagen engine into a compressor.) This assembly is called a stage. The cheapest compressors are single-stage units--they have one piston and cylinder. The air from the atmosphere is sucked into the assembly, compressed then sent to the tank. Next come two-stage compressors, which have a low-pressure stage and a high-pressure stage. The air from the first stage is compressed again by the second stage, which gives more pressure with less stress on the unit. It's easier on the compressor to take air from 2 atmospheres to 4 than it is to go from 1 atmosphere to 4. A three-stage compressor takes this doubly compressed air and compresses it again, and a four-stage compressor has a fourth compression step. Most of the people who buy three-stage compressors fill diving tanks with them--you need to be able to make 5000 psi to fill a diving tank, and three-stage compressors are good for that.
What qualifications do you need for marine biology when starting gcse stage?
lot and lots of gcses and to be brainy and work really hard (this answer is bad and useless) Actually, you need a lot of things, according to the University of Hawaii. 1 year College physics in labs (calculas/non-calculas) More knowledge on Chemistry would raise your chances of being accepted. Major in Biology Good grades in math(maths) good grades in English Would help to learn Scuba Diving, driving small boats, care for aquatic animals volunteer time in aquariums are a big advantage
What gear do you wear for scuba diving?
BCD, Regulator[first stage], mask, fins, snorkle + other accesories
What is it called the thing you put in your mouth when you go scuba diving?
It is called a regulator. To be specific, the part of the regulator that goes in your mouth is called the second stage of the regulator.
How much do scuba diving regulators weigh?
For bouyancy calculations, most regulators are assumed to weigh about 4 lbs. For recreational divers, they only carry one regulator, but technical divers may carry four (or more!) regulators on their doubles and various stage tanks.
What are the educational qualifications of deep sea diving?
"Deep" diving is diving farther than 120'. Though there are no educational qualifications per se, there are a number of certifications needed to do it safely. Certifications differ from agency to agency, but usually include: -Scuba diver -Advanced scuba diver, with deep dive training -Mixed gas diving -Multi-stage decompression diving -Diver rescue Specialized equipment includes: -Dry suit -Breathing gas mixtures such as trimix, heliox, etc (some use pure oxygen for decompression -Dive and decompression computers -Powerful underwater flashlights -More stuff I can't remember.
How scuba works?
how does scuba work someone please helpscuba (self contained underwater breathing apporatis) works primarally of two regulators a first stage and a second stage. the first stage is usually work by diaphrams but mosty pistons in newer models. it conects to your tank lowering the psi from your tank to a low pressure and disburses the air through a low pressure hose to your second stage regulator and a high pressure hose to your psi guage console and another low pressure hose for your power inflator. your second stage works by a round rubber diaphragm, when you inhale the vacume pulls the diaphragm against a valves that when pushed air is realeased the harder you inhale the more air is then realeased.There is an excellent answer under the question "How do you breathe underwater when you go scuba diving?"
What do you call a divers air tube?
Normal pressurized air is used for scuba diving. However, you can get mixed gases for SCUBA diving such as Nitrox, which is mixed gases of nitrogen and oxygen. This is used by deep sea diving, but it takes special training.
Is grade 2 the lowest or highest in breast cancer?
Stage 1 is the lowest and stage 4 as the highest.
At what stage of reaction do atoms have the highest energy?

How do you stage dive in Guitar Hero?
That would be cool, but you cant. Stage diving isn't an optional control in Guitar Hero. The only thing close is in Guitar Hero 3 where fans stage dive, but that's it
