What Makes Ice Melt Faster Essay
A. Explain the significance of the given factors in your project design plan:
• Problem statement
• Relevance of your testable question
I have lived in a place that during the winter, ice would form on the streets and sidewalks and have wondered why things such as salt or sand are used over other methods to help de-ice the surfaces? Why is salt or sand the most commonly used substances when addressing this issue?
If you live in a place that gets cold in the winter, you've probably seen trucks out spreading a mixture of sand and salt on the streets after a snowfall to help de-ice the road. Have you ever wondered how this works? This basic …show more content…
