Question

1. What is matter?
2. What are the three states of matter?
3. Which state holds its own shape?
4. What do you know about a gas's molecules?​

Answer 1

Answer:

1) Matter is anything that has mass and takes up space. Matter can be described in terms of physical properties and chemical properties. Physical properties and chemical properties of matter can change. Matter is composed of elements and compounds. Combinations of different substances are called mixtures.

2) They are very compressible (particles are widely spaced). There are three states of matter: solid; liquid and gas.

3) solids

A solid is something that can hold its own shape and is hard to squash. The particles in most solids are closely packed together and do not move around.

4) In solids, atoms and molecules are compact and close together. Liquids have atoms that are spread out a little more. The molecules in gases are really spread out, full of energy, and constantly moving around in random ways. ... Liquids can only fill the bottom of a container, while gases can fill it entirely.
