Physical Science : Physical Changes Through Heating

The video tutorial covers the states of matter, including solid, liquid, and gas, and how matter can change states under certain conditions. It explains physical properties like conductivity, luster, and malleability, and distinguishes between physical and chemical changes. The video also discusses pure substances, mixtures, and solutions, providing examples like fruit salad and saltwater. It concludes with a look at alloys and how different metals can be separated based on their melting points.
