What toxic gas is produced by fire?
carbon monoxide
Why do firemen wear their tanks upside down?
SCBA bottles that firemen use are mounted upside down because they are generally smaller than scuba tanks and the risk of damaging the valve while running through a burning building in zero viz is much higher than the risk of damaging a scube valve while swimming (or scootering) through a wreck or cave.
Why do firefighters not explode oxygen tanks?
Firefighters breathe from air tanks called SCBA’s (Self Contained Breathing Apparatus). These air tanks don’t explode when exposed to heat because they are filled with compressed air, not oxygen. The air tanks have a burst disk to prevent rupture from the increased pressure due to heat.
Are oxygen tanks heavier when full?
The oxygen contained in a full cylinder weighs about 20 lb. full cylinders of gas weigh a hell of a lot more than empty ones. Air is heavier than people think. If you put a cylinder around the eiffel tower, the air inside would weigh more than the tower does.
Will Oxygen tanks explode from heat?
It will not burn or explode. However, it does support and rapidly accelerates combustion. Here are some home safety precautions you should follow when you are using your oxygen: Notify the fire department and the electric company that you are using oxygen.
Can an oxygen tank explode if dropped?
Explosions are a potential risk with portable oxygen tanks if they are mishandled or dropped, posing a risk of serious and potentially life-threatening injury. Upon a certain degree of impact, the oxygen cylinder can ignite, causing an internal flash fire and causing the aluminum tank to burst.
Can a tank of oxygen ever be half empty?
An oxygen canister can never be half empty. oxygen or any gas molecule can take up all the space that they are in. So no matter how little or much oxygen there is in the container, it will always be full of oxygen.
Is a tank of gas ever half empty Why?
An oxygen tank can never be half empty. Since the amount of space between the gas particles matches the volume of its container, they would take up all the space in the tank. In this case, the gas particles would spread throughout the tank.
Can a container be half full of gas?
Of course a gas cylinder can be “half-filled.” The premise is false. Most “gas” cylinders (propane, etc) are held at a pressure where they are liquified. Thus, there is a finite amount of liquid that can fit in one, so “half-full” is just physics.
What could you do to change the volume of a gas?
To change the volume of a gas, you can either raise or lower the temperature. When the temperature becomes hotter, the gas will expand causing an increase in volume. On the other hand, when the temperature becomes colder, the volume of the gas will decrease.
Does Gas have a fixed volume?
Gases don’t have a fixed shape or a fixed volume. The particles move around all the time and spread out. This is why a gas fills its container. A gas can be compressed into a very small space – this pushes the particles closer together.
What is PV nRT called?
PV=nRT is called the ideal gas law in which pressure and volume of the gas are equal to the number of moles, the universal gas constant, and temperature.
How do we get PV nRT?
At constant temperature and pressure the volume of a gas is directly proportional to the number of moles of gas. At constant temperature and volume the pressure of a gas is directly proportional to the number of moles of gas. Or you could think about the problem a bit and use PV=nRT. N2O is placed in a piston.
