States of Matter and Particle Theory Quiz

Study Notes

Classification and Characteristics of Pure Substances

Pure substances can be classified as elements or compounds.
A pure substance has a fixed composition and a fixed set of properties, and it cannot be separated into simpler substances by physical means.

Energy Types

Kinetic energy is the energy of motion, whereas potential energy is the energy of position or stored energy.
Kinetic energy is related to an object's motion, whereas potential energy is related to an object's potential to do work.

Mixtures and Solutions

A mechanical mixture is a mixture of two or more substances in which each substance retains its chemical properties, whereas a solution is a homogeneous mixture of two or more substances.
In a solution, the particles of the substances are dispersed uniformly throughout the mixture.

Components of a Solution

A solution consists of a solute and a solvent.
The solute is the substance that is dissolved in the solvent, which is the substance that does the dissolving.

Particle Count

The number of particles in 12g of carbon depends on the type of carbon, as the molar mass of carbon varies depending on the isotope.

Mass and Weight

Mass is a measure of the amount of matter in an object, whereas weight is the force exerted on an object by gravity.
Mass remains constant, whereas weight changes depending on the gravitational field.

States of Matter

The three states of matter are solid, liquid, and gas.
These states are determined by the arrangement of particles in the substance.

Particle Theory of Matter

The five key points about particles are:
- Particles are extremely small and cannot be seen by the naked eye.
- Particles have mass and occupy space.
- Particles are in constant motion, with the motion increasing as the temperature increases.
- Particles have kinetic energy due to their motion.
- The arrangement of particles determines the state of matter.

Characteristics of Solids, Liquids, and Gases

Solids have a fixed shape and a fixed volume.
Liquids have a fixed volume but take the shape of their container.
Gases have neither a fixed shape nor a fixed volume.

State Changes

Matter can change states due to changes in temperature or pressure.
The arrangement of particles in a substance changes as it changes state.
