Study Notes

Matter and Its Properties

Matter is defined as anything that has both volume and mass.
Mass refers to the quantity of matter contained within an object.
Volume is the space occupied by an object.

Common Characteristics of Objects

All visible objects around us are composed of matter.

Properties of Matter

Properties are defining characteristics used to describe materials.
Weight is the gravitational force acting on an object.

Density and Physical Properties

Density measures the amount of matter in a specific volume.
Mass, volume, weight, and density are fundamental physical properties.
Physical properties can be observed without altering the substance, including attributes such as shape, size, color, smell, texture, and temperature.

Changes in Matter

Physical changes do not result in new substances; they only alter physical properties (e.g., changing size or state).
Chemical changes produce new substances, altering the identity of the initial material and often involve energy changes (e.g., combustion, rusting).

Examples of Properties and Changes

Common physical properties include color, density, size, and phase (solid, liquid, gas).
Chemical changes involve transformation into different substances, such as rust forming from iron and oxygen.

Chemical Properties

Chemical properties determine a substance's ability to undergo certain reactions (e.g., flammability, reactivity with other materials).

Observations and Examples

Observations in science often address physical properties like mass, density, volume, and color.
An example of a physical change is reshaping chalk, while an example of a chemical change is bread molding, resulting in new substances such as mold.

Distinguishing Changes

The key difference between physical and chemical changes lies in the creation of new substances; physical changes do not result in new compositions, whereas chemical changes do.
