How does temperature influence explosion hazards?

Temperature plays a significant role in influencing explosion hazards, particularly in relation to the vapor pressure of substances. As temperature increases, the kinetic energy of the molecules within a substance also increases. This higher energy facilitates more molecules transitioning into a gaseous state, which directly leads to an increase in vapor pressure.

Higher vapor pressure means that more flammable vapors are present in the air, creating an increased likelihood of reaching the flammability limits for combustion. If the concentration of these vapors becomes sufficient and is combined with an ignition source, the potential for an explosion is greatly enhanced. This is why understanding the relationship between temperature and vapor pressure is crucial for assessing explosion risks in environments where flammable substances are present.

In contrast, the other options relate to factors that either do not directly contribute to explosion hazards or misrepresent the effects of temperature on flammable materials.
