A ______ ______ has a similar purpose to the swim bladder
In this state, particles are tightly packed together and have a fixed position
What is solid?
The amount of space an object or substance takes up
What is volume?

A technique used when the object's shape is irregular and its dimensions cannot be easily measured
What is finding volume by displacement?
The density of a substance is directly related to its state of matter. Solid substances are generally more dense than liquids, which are more dense than gases.
What is the relationship between the density of a substance and the particle theory?
