Study Notes
Properties of Matter
- Properties are characteristics of materials, such as color and odor.
- You can observe many properties using your senses.
- You can measure some properties by comparing them to a standard unit.
- Volume is the amount of space a material takes up and can be measured in liters and milliliters.
- Some properties can be identified by observing how a material interacts with other materials or energy.
- Copper conducts electricity.
- Some materials are magnetic, meaning they are attracted to magnets.
- Solubility refers to a substance's ability to dissolve in another material.
- All matter is composed of elements.
- An element consists of only one type of atom.
- An atom is the smallest part of an element that retains the element's properties.
Chemistry Notes
- The atomic theory states that all matter is made up of small particles called atoms.
- Compounds are substances composed of two or more elements.
- A molecule is the smallest unit of a compound that retains the compound's properties.
- Different molecules can be formed by varying the number or types of atoms in a molecule.
States of Matter
- The three main states of matter are solid, liquid, and gas.
- The state of matter depends on the motion of its atoms or molecules.
- Temperature is a measure of how fast particles are moving.
- Temperature can be measured in Celsius (°C) or Fahrenheit (°F).
- Mass is the amount of matter in a substance and is measured in grams or kilograms.
- Volume is the amount of space an object occupies, also measured in grams or kilograms.
- Solids and liquids have a definite volume, but gases expand to fill their container.
Physical and Chemical Changes
- Texture is the surface material of a material.
- Hardness is a property that can be felt in solids.
- A solid has a definite shape and volume.
- A liquid has a definite volume but not a definite shape.
- A gas has no definite shape or volume.
- Matter can change size and shape.
- A physical change alters the properties of matter without creating a new type of matter.
- A change in temperature is a physical change.
- Freezing is the process of a liquid turning into a solid.
Chemistry Notes
- When a solid is heated, its particles gain energy and can move past each other.
- The melting point is the temperature at which a solid turns into a liquid.
- The freezing point is the temperature at which a liquid turns into a solid.
- Water's melting point is 0°C or 32°F.
- Evaporation occurs when particles leave a liquid and become a gas.
- Evaporation occurs when particles at the surface of a liquid move upward with enough speed.
- Boiling point is the temperature at which gas particles move quickly upward through a liquid, forming gas bubbles under the surface.
- Water's boiling point is 100°C or 212°F.
- A chemical change produces one or more new substances.
- During a chemical change, substances rearrange to form new substances.
- Evidence of a chemical change includes the release of heat or light, a change in color, a new smell, gas bubbles, or the formation of a solid.
- The Law of Conservation of Matter states that the total mass of matter remains constant during chemical or physical changes.
- In a chemical change, all particles from the original substance end up in the new substance.
- A chemical reaction occurs when substances transform into new substances.
Mixtures and Solutions
- In a mixture, different materials are combined but retain their individual properties.
- A solution is a mixture where substances are evenly spread out.
- The solute is the substance dissolved in the solution.
- The solvent is the substance in which the solute is dissolved.
- Solution components retain their properties but are usually difficult to separate.
- All solutions are mixtures, but not all mixtures are solutions.
