Pre-lab question #4: Distinguish between volatile and nonvolatile substance. The word "volatile" refers to a substance that vaporizes readily. Volatility is a measure of how readily a substance vaporizes or transitions from a liquid phase to a gas phase. A A (volatile/nonvolatile) substance refers to a substance that does not readily evaporate into a gas under existing conditions. A AA (volatile/nonvolatile) substance is one that evaporates or sublimates at room temperature or below.
