Study Notes

Chemical Properties

Characteristics that indicate a substance's ability to transform into a new substance with different properties.
Measurable or observable attributes essential for classification.

Physical Properties

Observable and measurable characteristics that do not alter the substance's identity.
Can be assessed without causing any transformation into a new substance.

Matter

Defined as anything that possesses mass and occupies space.
All entities in the universe are composed of matter, making it a fundamental concept in science.

Inertia

A property that describes the resistance of an object to changes in its state of motion.
Essential for understanding concepts related to forces and movement.

Mass

Represents the quantity of matter contained within an object.
A fundamental property influencing the behavior of objects under gravitational forces.

Volume

Refers to the total space that a substance occupies.
Essential for calculations in various scientific fields, including chemistry and physics.

Weight

The measure of the gravitational force exerted on an object, correlating with its mass.
Weight varies with gravitational pull, which changes based on location (e.g., on different planets).

Density

Indicates the mass of a substance relative to its volume, calculated as mass per unit volume.
Commonly used to differentiate substances, especially in liquids and solids.

Physical Change

Involves alterations in the physical properties of a substance without changing its chemical identity.
Examples include changes in state (solid to liquid), size, or shape.

Chemical Change

Occurs when a substance undergoes a transformation leading to the formation of new substances with unique properties.
Often evident through indicators like color change, gas production, or temperature change.

Characteristic Properties

Unique properties specific to a substance that can be utilized for identification purposes.
Important in experiments and practical applications for distinguishing between different materials.

Gravity

The force that governs the attraction between two objects, depending on their masses and the distance between them.
A fundamental force crucial in various scientific explorations, including astronomy and physics.
