Question

Select all of the characteristics that gases in compressed gas systems may have.

1) They may be flammable
2) They may be explosive
3) They may be toxic
4) They may displace air

Answer 1

Compressed gas systems may contain gases that are flammable, explosive, toxic, or capable of displacing air. These gases have no definite shape or volume and can have predictable behaviors based on their physical properties.

Step-by-step explanation:

The characteristics that gases in compressed gas systems may have include:

Flammability: They may be flammable, meaning they can catch fire and burn.

Explosiveness: They may be explosive, indicating that they can cause destructive explosions.

Toxicity: They may be toxic, posing health hazards if inhaled or contacted.

Displacement of Air: They may displace air, reducing oxygen concentration and potentially leading to asphyxiation.

Gases are one of the states of matter with no definite shape or volume, tending to fill whatever container they are in and have very low densities. Their behavior can be predicted based on the physical properties of pressure, volume, temperature, and amount of gas.
