💨 Chemistry by Chang – Problem 1.29: Converting Speed Units | Steemit Science

in Popular STEM29 days ago

Hello Steemit learners! 👋⚗️

This problem is from Raymond Chang’s Chemistry (14th Edition), within Chapter 1: Measurement and the Properties of Matter. It deals with unit conversions, one of the most practical and frequently used skills in chemistry and physics.


🔹 Problem:

1.29 The average speed of helium at 25°C is 1255 m/s.
Convert this speed to miles per hour (mph).


In this exercise, we combine metric-to-imperial conversion and time unit conversion to express the same physical quantity — speed — in a more familiar form.

Understanding how to manipulate conversion factors is essential for comparing data across systems and interpreting physical phenomena correctly.
