No firm information is available on the temperature differences in variable voltage devices. [5] The length of time that the e-cigarette vapor is being heated within the device also affects the e-cigarette vapor properties. [41] When the temperature of the heating element rises, the temperature of the e-cigarette vapor in the air rises. [41]
The temperature of the gases leaving the vent ranges from about 100 to 1,000 °C (210 to 1,800 °F). [4] The steam forms when groundwater is superheated by hot rock, then flashes (boils due to depressurization) as it approaches the surface.
Vapor pressure [a] or equilibrium vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed system. The equilibrium vapor pressure is an indication of a liquid's thermodynamic tendency to evaporate.
At the surface expression of such hydrothermal systems, low-temperature volcanic gases (<400 °C) are either emanating as steam-gas mixtures or in dissolved form in hot springs. At the ocean floor, such hot supersaturated hydrothermal fluids form gigantic chimney structures called black smokers , at the point of emission into the cold seawater .
Temperature-dependency of the heats of vaporization for water, methanol, benzene, and acetone. In thermodynamics, the enthalpy of vaporization (symbol ∆H vap), also known as the (latent) heat of vaporization or heat of evaporation, is the amount of energy that must be added to a liquid substance to transform a quantity of that substance into a gas.

The e-liquid reaches a temperature of roughly 100-250 °C within a chamber to create an aerosolized vapor. [7] Variable voltage devices can raise the temperature. [30] A glycerin-only liquid vaporizes at a higher temperature than a propylene glycol-glycerin liquid. [30]
A mixture of two agents in a vaporizer could result in unpredictable performance from the vaporizer. Saturated vapor pressure for any one agent varies with temperature, and plenum vaporizers are designed to operate within a specific temperature range.
