Summary of Matter

00:00:00 - 00:10:00

In this video, a student explains the different types of matter and how they are distinguished from each other. A demonstration is then given on how to separate two different liquids using filtration. The student asks students to complete a quiz on the topic before moving on to the next lesson.

• 00:00:00 In this chemistry lesson, the different types of matter are introduced, and how they are distinguished based on their mass, space taken up, and boiling point. Finally, a demonstration is given of how to separate two different liquids using filtration.
• 00:05:00 In this video, a flask of liquid is collected at one end and a flask of higher boiling point liquid is retained at the other. Matter can be classified as either a pure substance or a mixture of substances, and a pure substance can either be an element which consists of only one type of atom, or a compound which consists of more than one type of atom. Chemically combined, a mixture of substances consists of more than one substance. Physical properties, such as smell, color, solubility, boiling point, and volatility, can be observed without changing the identity of the substance. Chemical and physical changes are differentiated using examples of chemical and physical changes, such as the formation of rust or freezing of water.
• 00:10:00 In this video, a student explains that iron rusts when it is exposed to air, and that this chemical change concludes the lesson. The student then asks students to complete a quiz on the topic before moving on to the next lesson.
