General Chemistry Chapter 1 and 2 Test | Latest Update | 2024/2025 | Already Passed What are the main characteristics of matter in terms of its states? The main states of matter are solid, liquid, and gas. Solids have a definite shape and volume, liquids have a definite volume but take the shape of their container, and gases have neither definite shape nor volume, expanding to fill their container. How do you convert between different units of measurement for volume, such as lite...
