If V1 = V2 => p1 / T1 = p2 / T2 <=> p2 = p1 * T2 / T1
Let's assume that T1 = 20 C Degree = 313 K
=> p2 = p1 * 343/313 => p2 = 1.10 p1 which means 10% higher pressure.

When to use a fire extinguisher?
You should use a fire extinguisher when a fire is small and contained, such as a small grease fire on a stove or a trash bin fire. It is important to remember that you should only attempt to use a fire extinguisher if you have been trained in its proper use and if it is safe to do so. If the fire is large or spreading quickly, evacuate and call emergency services.
What is the white stuff that is in fire extinguishers?
The white stuff in fire extinguishers is typically a chemical called dry chemical powder or monoammonium phosphate. This powder is a fire suppression agent that is effective for extinguishing different types of fires, such as those involving flammable liquids, gases, and electrical equipment. When released, the powder smothers the fire and helps to cool the fuel, preventing it from reigniting.
What will happen if you remove syphon tube from the CO2 fire extinguisher?
If you remove the siphon tube from a CO2 fire extinguisher, the extinguisher will not work properly. The siphon tube is responsible for drawing and releasing the CO2 gas from the extinguisher. Without it, the CO2 gas will not be able to flow out effectively, rendering the extinguisher ineffective in suppressing fires.
What fire extinguisher do you use on a electrical fire?
Water is good as it will cut off oxygen and cool the heat source.
Powder and foam will smother to cut off oxygen.
Carbon Dioxide (CO2) will cut off oxygen but blast of gas may spread ther fire by blowing light material such as paper causing it to set fire to other things.
Don't use water on oil, or a chip pan fire.
What is an indicator that a fire extinguisher is usable?
Most extinguishers have a pressure gauge which has a Red Zone marked for full pressure. Just look to see if the needle indicated pressure at near the Full mark. Also, most extinguishers are filled with powder. This powder can pack down and cake when not agitated. It is a good idea to turn the extinguisher over, upside down several times. You will feel the powder move about inside the housing.
Why would cylinder 2 3 not fire on a 1992 ford ranger 2.3l 4 cylinder?
Hi,
Offhand, I can think of a couple of possibilities immediately. The first would be a collapsed hydraulic lifter, preventing a valve from opening. Maybe a bent push rod (between the lifter and rocker arm).
If it's a lack of spark, it could be the ignition coil. Chances are that you have one coil for every two cylinders, or the control for the coil not delivering the proper pulse.
The spark plug wires are usually made with a carbon conductor and possibly one or both leads have breaks in them, but that'll usually just cause a weak spark or even the wires could be reversed and firing when they shouldn't.
That's, `off hand`.
Hope it helps,
Cubby
