Which statement best describes the atoms of the gas neon?
Which liquid is the most viscous?
Which best describes why a liquid needs a container when a solid does not?
An analogy makes a comparison between objects based on their similar qualities. Cassidy wanted to create an analogy for the motion of atoms in solids, liquids, and gases, so she compared them to marbles in a tray.
Density involves the amount of a material in a certain volume. When a material changes phases, it changes in density in a predictable way as the amount of material stays the same but the molecules get farther apart or closer together. Water has solid and liquid states that do not follow these predictions of density in the phases of matter.
Which statement describes all solids?
Gerry is looking at salt under a powerful microscope and notices a crystalline structure. What can be known about the salt sample that Gerry is looking at?
Density describes how much mass is contained in a certain volume. Knowing how far apart molecules are in each state, which best ranks solids, liquids, and gasses from least dense to most dense?
Gold’s natural state has a definite shape and a definite volume. What is gold’s natural state(s)?
Mercury’s natural state is where the atoms are close to each other but are still free to pass by each other. In which state(s) could mercury naturally exist?
