Standard Temperature And Pressure (STP)

Imagine trying to fit a jigsaw puzzle together without knowing the correct starting piece or edge. Just as a specific piece needs to be used as a reference point to make progress on the puzzle, scientists use standard temperature and pressure (STP) as a reference point to ensure consistency and comparability in experiments. In this analogy, the jigsaw puzzle represents scientific experiments, the starting piece is the STP value of 0°C and 101.3kPa, and the process of fitting other pieces around it mimics how scientists use STP to compare results across different conditions.
