Evaporation rate specifically refers to the speed at which a liquid transitions into vapor. This process occurs at any temperature, as opposed to boiling, which is a more vigorous transformation that happens at a specific boiling point under given pressure conditions. The evaporation process is influenced by factors such as temperature, surface area, and air movement but is fundamentally about how quickly molecules at the surface of a liquid gain enough energy to enter the gas phase. Understanding the evaporation rate is crucial in safety and environmental contexts, particularly when dealing with flammable substances and exposure risks, as it helps assess the potential for vapor formation and concentration in the air.
