Theme 4: Please Pass the Salt
Files
Description
All matter is made up of atoms and molecules. Even though we can’t see them with our bare eyes, these tiny particles are constantly moving. The temperature of a substance is a measure of its average kinetic energy (the energy it has due to the motion of the particles). As the temperature increases, particles gain more energy, move more quickly and spread further apart.
No matter where one lives in Illinois, you are impacted by winter weather. Deicing and snow removal account for a large portion of state and local highway budgets. Salt is commonly used for melting snow and ice. Salt lowers the temperature at which water freezes and makes it difficult for the water to bond into rigid crystals of which ice is made. As the air temperature drops, the efficiency of salt melting the ice also decreases.
