Winter Wonders: The Science of Cold
By Emily Eggleston | December 26, 2011
When it comes to science, temperature matters. And when it comes to Wisconsin, things get really, really cold. When the temperature drops, the world around us changes in a practical and scientific sense. For instance, my car is less likely to work (though that may be a function of age rather than weather), and the percentage of water maintaining a crystalline configuration goes up. There are a lot of things to wonder about how a cold world functions, scientifically. These are some of my questions, and their answers:
1. Will the gasoline in my car’s tank actually ever freeze into a gas-cube?
2. Why is wool so warm?
3. Why do some snowflakes look intricate and lacy, while others seem shapeless?
