☀️ Chemistry by Chang – Problem 1.31 | Speed of Light and Distance from the Sun | Steemit Science

in #chemistry19 days ago

Hello Steemit science enthusiasts! 👋🌍

Here’s another thought-provoking problem from Raymond Chang’s Chemistry (14th Edition), part of Chapter 1: Measurement and the Properties of Matter.
This exercise blends physics and chemistry by exploring how long it takes for sunlight to travel from the Sun to Earth — a great example of dimensional analysis in action.


🔹 Problem 1.31:

How many minutes does it take light from the Sun to reach Earth?
(The distance from the Sun to Earth is 93 million miles; the speed of light = ( 3.00 \times 10^{8} \text{ m/s} ).)


This problem is a classic example of applying unit conversions and rate calculations.
You’ll need to convert miles to meters and then use the relationship between distance, speed, and time

Finally, express the result in minutes for a meaningful real-world interpretation.

Isn’t it fascinating that sunlight we see now actually left the Sun several minutes ago? ☀️✨
