Torrance

Torrance is a unit of measurement used to quantify the vapor pressure of a substance, particularly liquids, indicating how much of the liquid's vapor (gas) exists above its surface at a specific temperature. Named after economist Eli Torrance, it helps scientists and engineers understand a liquid's volatility, or how easily it evaporates. A higher Torr value means the substance produces more vapor and evaporates faster, which is important in fields like chemistry, manufacturing, and safety. Essentially, it provides a standardized way to compare how quickly different liquids turn into vapor under certain conditions.
