Properties of Matter

Fun Facts

  • Styrofoam cannot be dissolved by water.
  • Glue can be dissolved in water.
  • Slime does not dissolve in water.

Why Do We Need To Know About Dissolve

Learning about how things dissolve helps us figure out why some materials mix well and why we use certain materials for makeup or health products. For example, knowing why acetone can get rid of nail polish but doesn’t dissolve salt explains why it’s picked for nail polish remover.

This idea isn’t just for simple stuff; it’s also important in big fields like aerospace engineering. Engineers need to know how materials will behave, including if they’ll dissolve, when designing things like rockets. This shows how knowing about dissolving is key in many science and engineering jobs.

Frequently Asked Questions

Which property did Zoe use to figure out which metal was sodium and which was iron?
Zoe knew that iron is magnetic and sodium is not so she tested each with a magnet.
What property of sodium metal did you observe?
Sodium metal reacts with water causing an explosion.
Which is more dense: sulfur hexafluoride or helium? How do you know (what evidence did you see)?
Sulfur hexafluoride is more dense than air. When placed inside a balloon, the balloon falls to the ground. Helium is less dense than air. A helium-filled balloon floats in air. A boat filled with air floats on top of Sulfur hexafluoride gas.
