How does propane's vapor pressure change with temperature increase?

Propane is a liquefied gas that demonstrates a definitive relationship between temperature and vapor pressure. As the temperature increases, the kinetic energy of the propane molecules also rises. This increase in molecular activity leads to more molecules transitioning from the liquid phase to the vapor phase, which ultimately raises the vapor pressure of the propane.

This behavior is characteristic of most volatile substances, where higher temperatures result in more vapor being produced. This means that as the surrounding temperature goes up, the pressure exerted by the vapor above the liquid also increases. Understanding this principle is crucial for handling propane safely and effectively, as it plays a significant role in storage, transportation, and usage scenarios.

Other options present alternative scenarios that do not align with the established physical properties of gases, helping reinforce the understanding of how temperature directly influences vapor pressure in propane.
