In addition, the vapor pressure of this substance cannot be ignored. Vapor pressure is the pressure exerted by the molecules in the gas phase when the substance is in equilibrium with the liquid phase. The vapor pressure increases with temperature, which is due to the intensified thermal motion of molecules and the increased tendency to escape from the liquid phase. The magnitude of the vapor pressure affects its volatilization rate, which is related to its diffusion and transport in the environment.

This is a summary of the physical properties of 3,3,4,4-tetrafluoro-4-iodine-1-butene. The intertwined properties constitute its unique physical "portrait", laying the foundation for chemical research and application.
