Test Review-SLG, Classification of Matter, and Properties of Matter General Science Test Review-SLG, Classification of Matter, and Properties of Matter

List the characteristics of a solid. Definite volume Definite shape Crystalline, orderly particle structure Particles held tightly in place Least amount of KE

When a sample of matter is heated, its particles _____________________. Move more quickly

As the temperature of a gas increases, the volume of the gas will __________________ if the pressure remains the same. increase

List the 3 parts of the kinetic theory. All matter is composed of particles The particles are in constant random motion The particles collide with each other and the walls of their container

List the characteristics of a liquid. Definite volume No definite shape More KE than a solid, but less than a gas Enough KE to escape orderly arrangement Can flow

Why is water unusual? Water expands as it goes from liquid to a solid (most other substances contract) due to its polarity

Compare the speed of the particles in a solid compared to a gas. Particles move much slower (vibrate in place)

List the characteristics of a gas. No definite volume No definite shape Most KE

What happens to most matter when it is heated? The particles gain KE and break attractions to neighboring particles; they take up more space

List the characteristics of plasma. Most similar to a gas No definite shape No definite volume Composed of positively and negatively charged particles

Define heat of fusion. The amount of energy required to change a mass of a solid to a liquid at the melting point

Define heat of vaporization. The amount of energy required to change a liquid to a gas at the boiling point

Define a colloid and give an example. A mixture with particles large enough to scatter a beam of light; milk or fog

What happens when a log burns on a fire? Mass is conserved; though the ashes have much less mass than the log, matter or mass has not been lost

What is another name for a homogeneous mixture? solution

Define a mixture. a material made up of two or more substances that can be easily separated by physical means

What is the Tyndall Effect? scattering of light by colloidal particles

Define a suspension and give an example. heterogeneous mixture containing a liquid in which visible particles settle; pond water

What two categories is matter classified into? Substances and mixtures

What is distillation? process for separating substances in a mixture by evaporating a liquid and recondensing its vapor

What categories can substances be broken down into? Elements and compounds
