Additional Information
- Vapor Pressure: The vapor pressure of ethanol increases with temperature, indicating that more ethanol molecules escape into the vapor phase as temperature rises.
- Applications: Ethanol is commonly used in the production of alcoholic beverages, as a solvent, and in various industrial applications.
- Health and Safety: Ethanol is flammable, and its vapors can be harmful if inhaled in large quantities. Adequate ventilation is essential when working with ethanol.
Understanding Vapor Pressure
- Vapor Pressure Definition: Vapor pressure is the pressure exerted by a vapor in equilibrium with its liquid or solid form at a given temperature.
- Temperature Dependence: As temperature increases, the kinetic energy of molecules also increases, leading to higher vapor pressures.
