Study Notes
Understanding Matter
- Matter is defined as anything that occupies space and has mass.
- Mass measures the amount of matter in an object and remains constant regardless of location.
- Units of mass include grams (g), kilograms (kg), and milligrams (mg).
Properties of Mass
- Mass determines how heavy an object is; a bowling ball has more mass than a feather.
- Mass is independent of gravity and does not change with the object's position.
Volume of Matter
- Volume refers to the space occupied by an object; a larger mass generally leads to greater volume.
- Liquid volume can be measured in liters, milliliters, ounces, quarts, and cubic meters.
States of Matter
- Matter exists in three primary states: solids, liquids, and gases, each with distinct particle behaviors.
- Solids maintain a fixed shape due to closely packed particles locked in place, allowing only vibration.
Properties of Solids
- Solids cannot be compressed or change shape; examples include coins, books, and erasers.
- The particles in solids are arranged in fixed positions, contributing to their rigidity.
Properties of Liquids
- Liquids have a definite volume but take the shape of their containers.
- When pouring a liquid, its volume remains unchanged despite the change in shape.
- Liquid particle movement is influenced by energy; heating a liquid increases particle speed.
