Matter and its Properties Quiz

The 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 a definite shape nor volume and can flow.

Matter is anything that has mass and volume. Mass refers to the amount of material in an object, while volume refers to the amount of space it occupies.

The inter-conversions of the states of matter can be explained by the kinetic particle theory. This theory states that matter is composed of particles (atoms, molecules) that are in constant motion. Heating a solid can convert it to a liquid (melting) and further heating can convert it to a gas (vaporization). Cooling a gas can convert it to a liquid (condensation) and further cooling can convert it to a solid (freezing).

<p>In solids, particles are closely packed together in a fixed arrangement. In liquids, particles are close together but not in a fixed arrangement. In gases, particles are far apart and move randomly.</p> Signup and view all the answers
