🌌 Chemistry by Chang – Problem 1.37 | Unit Conversions: Astronomical and Everyday Distances | Steemit Science
Hello Steemit science enthusiasts! 👋✨
This problem comes from Raymond Chang’s Chemistry (14th Edition), in Chapter 1: Measurement and the Properties of Matter.
It explores unit conversions across both astronomical and everyday contexts — from light-years to centimeters!
🔹 Problem 1.37:
Carry out the following conversions:
(a) 1.42 light-years → miles
(A light-year is the distance traveled by light in a year, or 365 days; the speed of light is ( 3.00 \times 10^{8} \text{ m/s} )).
(b) 32.4 yd → centimeters
(c) 3.0 x 10^{10} cm/s → ft/s
This exercise is an excellent application of dimensional analysis, connecting measurements that range from cosmic distances to practical, everyday scales.
It reinforces how the same mathematical principles apply whether we’re talking about galaxies or inches!
📸 Here’s my complete step-by-step conversion for each part:
From light-years to feet per second — science truly covers every scale of the universe! 🌠
