What must happen to compressed oxygen before it can be inhaled?
Compressed oxygen must first be filtered to remove any impurities or contaminants. It is then typically stored in a tank or cylinder under high pressure. Before inhalation, the compressed oxygen is delivered through a regulator that reduces the pressure to a safe level for breathing.
What must be done to make oxygen a liquid?
To make oxygen a liquid, it must be cooled to a temperature below its critical temperature of -118.57 degrees Celsius and be subjected to high pressure. This will cause the oxygen molecules to come close together and transition from a gas to a liquid state.
What two elements must a silicate have?
Silicon and oxygen are the two elements that must be present in a silicate mineral. Silicates are the most common minerals on Earth and are characterized by a silicate tetrahedron structure, where one silicon atom is surrounded by four oxygen atoms.
What two substances must be present for iron to rust?
Iron must come into contact with oxygen and water for it to rust. This process is known as oxidation, where the iron reacts with oxygen in the presence of water to form iron oxide, the reddish-brown compound known as rust.
What must be done to oxygen to change it to a liquid?
To change oxygen gas into a liquid, it must be cooled to a temperature below its critical temperature of -118.57 degrees Celsius. This can be achieved by compressing the gas while simultaneously cooling it.
During an engines intake stage what passages inside the cylinder head must the incoming air-and-fuel mixture flow through in order to enter the cylinder?
Intake valve must be open
Can you replace valve seals without taking the head off a Mazda b2200?
To replace the valve stem seals with the head on you must bring each cylinder up to top dead center, pressurize the cylinder with an air chuck screwed into the spark plug hole. (this prevents the valves from dropping into the cylinder) Now the seals on that cylinder can be replaced. The process is repeated on each cylinder. Note: you must prevent the engine from rotating when the cylinder is pressurized.
What are the signs of a bent valve?
IF there is no compression in one or more cylinder, you either have a bent valve, a burned valve or a bad head gasket. In any case, the head must be removed if you plan to repair the engine.
What needs to be open to make the flame blue on a Bunsen burner?
In order to have a proper blue flame the air valve must be opened enough to allow enough oxygen to enter during the combustion process. Be aware that too much oxygen will not allow the gas to ignite and too little oxygen is noticed by a yellow flame caused by incomplete combustion and the burning of carbon.
What is the last valve oxygen depleted blood must pass through before pumping to the lungs?
The last valve oxygen-depleted blood must pass through before being pumped to the lungs is the pulmonary valve. This valve separates the right ventricle from the pulmonary artery and prevents blood from flowing back into the heart. Once the blood passes through this valve, it enters the pulmonary artery and travels to the lungs for oxygenation.
How do you replace valve seals on a 1995 Eagle Talon?
You can do it on the car by pumping compressed air in to the cylinder (must be at TDC). The compressed air will keep the valves pushed up while you remove the valve springs. The downside to this that you will have to have a special tool to compress the valve springs to remove the keepers and you can only do 1 cylinder at a time because each piston must be at top dead center.
How do you change the valve stem seals on a 1997 Mazda 626 2l?
The cylinder head must be removed. If you go to that much trouble, it would be best to resurface the head and do a valve job.
During an engine's intake stage what passages inside the cylinder head must the incoming air-and-fuel mixture flow through in order to enter the cylinder?
Intake valve/valves.
What is the valve clearance for a 1981 Yamaha virago 750?
The valve clearance is: INTAKE 0.004in. (0.10 mm) EXHAUST 0.006IN. (0.15 mm) You must the rear cylinder at T for tdc and the front at I for tdc. Wheadjusting valves.
During an engines intake stage what passages inside the cylinder head must the incoming air and fuel mixture flow though in order to enter the cylinder?
Intake valve must be open to allow atomized fuel mixture to enter cylinder--than all valves are closed during compression stroke 4- stroke engine 1) intake valve open to allow fuel mixture to enter cylinder 2) compression stroke all valves closed 3) ignition stroke mixture is ignited by spark from spark plugs 4) exhaust stroke--exhaust valve is open to allow residue to escape
Where is the thermostat o a 2001 Subaru Forester?
The thermostat of a 2001 Subaru Forester can be found under the hood of the vehicle. The radiator valve cap must be opened to reveal the thermostat.
During an engine intake stage what passages inside the cylinder head must the incoming air and fuel mixture flow through in order to enter the cylinder?
The intake runner and the intake valve (naming only the head assembly).
