Chemistry is the study of matter and how it changes. Matter is everything that has mass and takes up space, like the air we breathe, the water we drink, and the objects we use every day. Chemistry helps us understand what things are made of and how they interact with each other. For...

Derrick has taught biology and chemistry at both the high school and college level. He has a master's degree in science education. Cite this lesson All matter is characterized based on its properties. In this lesson, you will learn about the different chemical properties of matter and ways to...
Photonshave no mass, so they are an example of something in physics that isnotcomprised of matter. They are also not considered "objects" in the traditional sense, as they cannot exist in a stationary state. Phases of Matter Matter can exist in various phases: solid, liquid, gas, or plas...
Liquids exist in a relatively small part of the enormous range of temperatures and pressures existing in the universe. Nevertheless, they are of vital importance for physics and chemistry, for technology, and for life itself. A century of effort since the pioneering work of van der Waals has ...
Chemistry is usually thought to be more difficult than other subjects, at least for the beginners. There are some reasons for this idea. For one thing, chemistry has a very specialized vocabulary(学科专用语汇). At first, studying chemistry is like learning a new language. Also, some concepts...
