Study Notes
Physical and Chemical Properties of Matter
- Solid matter has a fixed structure and packs more mass into a given volume than a liquid or gas, except for water which decreases in density when it freezes.
- Reactivity is a chemical property, involving the ability of matter to interact and create new substances through chemical processes.
- Five types of chemical reactions are combustion, synthesis, decomposition, single replacement, and double replacement.
- Mass is a physical property, measurable using a balance, and influenced by both the amount and density of matter.
- Corrosion is a chemical property where oxygen reacts with the surface atoms of a metal, leading to the destruction of the metal's integrity.
- Understanding physical and chemical properties of matter is crucial in scientific, technical, and daily life applications.
- Matter exists in four states: solid, liquid, gas, and plasma, with plasma being rarer and matter on Earth mostly existing in solid, liquid, or gas form.
- Examples of matter in different states include solid (brick, ice), liquid (water, mercury), gas (water vapor, helium), and plasma (the Sun).
- Solids have high density, a definite shape, and volume, while liquids and gases have less density and take the shape of their container.
- Gold is an example of a metallic solid, maintaining a constant shape and volume due to its fixed molecular structure.
- Water reaches its maximum density at 4 degrees Celsius and freezes solid at 0 degrees Celsius.
- Corrosion can cause significant damage to infrastructure materials such as steel and bridge supports.
