Students will learn how to categorize matter as either pure substances or mixtures. Students will apply tests, based on physical properties of matter samples, to determine whether a mixture is ...

A homogeneous mixture is also known as a solution. It is a substance composed of two or more substances that are distributed uniformly at a molecular level or microscopic. In easier terms, homogeneous ...

This article brings you the CBSE Class 9 Science Notes for Chapter 2 - Is Matter Around Us Pure (Part-II). This part is a continuation of CBSE Class 9 Science Notes for chapter 2 - Is Matter Around Us ...

A research team simulated phase separation in colloidal suspensions. By treating colloid particles as undeformable highly viscous liquid droplets suspended in a solvent, they predicted the kinetics of ...

Highly purified crystals that split light with uncanny precision are key parts of high-powered lenses, specialized optics and, potentially, computers that manipulate light instead of electricity. But ...

These Aha! resources are also available in Spanish! A funny thing happens when you add cornstarch to a liquid and heat up the mixture: It gets really, really thick, or viscous. That thickening process ...
