Introduction to Matter - Study Notes

Introduction to Matter - Study Notes

• Matter is anything that has mass and takes up space. Everything around you is made of matter.
• Chemical properties describe how a substance reacts with other substances to form new substances. Examples include flammability (ability to burn) and reactivity with water.
• Physical properties describe the characteristics of a substance without changing its chemical composition. Examples include color, texture, density, melting point, and boiling point.
• Components of Matter: Matter is composed of atoms and molecules, which join to take up space and define shape and form.
• Mass is a measure of the amount of matter in an object.
• Weight is the force of gravity acting on an object's mass.
• Volume is the amount of space an object occupies.
• Density is the mass of a substance per unit volume.
• Physical changes in matter alter the physical form of a substance, without changing its chemical composition. Examples include melting, freezing, and evaporating.
• Chemical changes in matter result in the formation of new substances with different chemical properties. Examples include burning, rusting, and reactions with acids.
• Energy and matter are related: Changes in matter often involve energy transformations (energy is released or absorbed).
• Density and Temperature: Density of a substance changes with temperature, as temperature effects the density of space within matter. Often, as temperature rises, the substance expands and density decreases.
