True or False: Propane can displace oxygen needed to sustain life.

Propane is a hydrocarbon gas that, when released in a confined space, can indeed displace oxygen. This phenomenon occurs because, as propane accumulates in an enclosed area, it occupies the space that would otherwise be filled with oxygen, leading to lower oxygen levels. Without adequate oxygen, staying in such an environment can pose serious health risks, including unconsciousness or suffocation due to insufficient oxygen for breathing.

Understanding that propane poses a displacement risk highlights the importance of proper ventilation when using propane in any setting and underscores the need for caution when handling and storing propane. Thus, the statement is true, as propane can displace the necessary oxygen needed for life, especially in confined or poorly ventilated areas.
