Matter and Its Properties

Matter

Anything that occupies space and has mass or weight.

Volume

The space occupied by matter.

Mass

The measurement of the amount of matter in an object. It remains constant regardless of location.

Weight

Measures the gravitational force acting on an object. It changes with gravity.

Gravity

The mutual force of attraction between all objects in the universe.
The greater the mass of an object, the stronger its gravitational pull.
As the distance between objects increases, the gravitational attraction between them decreases.

Properties of Matter

Physical Properties

Characteristics that can be observed or measured without changing the chemical composition of the substance.
Include color, transparency, appearance, taste, odor, electrical and thermal conductivity.

Intensive Properties

Properties that do not depend on the amount of matter present.
Include luster, malleability, ductility, conductivity, hardness, melting point, freezing point, boiling point, condensation point, density, and resistance.

Extensive Properties

Properties that depend on the amount of matter present.
Include mass, weight, volume, and length.

Chemical Properties

Describe how a substance reacts with other substances during chemical reactions.

States of Matter

Solid

Has a definite volume and shape.
Examples include stone, sand, sugar, wood, and iron, which can be picked up and moved around.

Liquid

Has a definite volume, but no definite shape.
Examples include water, alcohol, evaporated milk, and condensed milk, which flow and can be poured.

Gas

Has no definite volume or shape.
Examples include air, oxygen, and carbon dioxide, which expand to fill the container they are in.

Earth’s Atmosphere

The layer of gases surrounding Earth.
Consists of 78% nitrogen, 21% oxygen, and 1% other gases.
Protects life on Earth by filtering harmful radiation from the Sun.
Is divided into five main layers: Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere.

Troposphere

The lowest layer of the atmosphere.
Extends from ground level to about 10 km (6 miles) above sea level.
Contains 75% of all air in the atmosphere.
Most clouds are found here because 99% of the atmospheric water vapor is present in this layer.
Temperature and air pressure decrease with increasing altitude.

Stratosphere

Located above the troposphere and extends to about 50 km (31 miles) above the ground.
Contains the ozone layer which absorbs UV radiation from the Sun.
Temperature increases with increasing altitude due to the absorption of UV radiation.

Mesosphere

Lies above the stratosphere and extends to approximately 85 km (53 miles) above the ground.
Temperature decreases with increasing altitude.
Most meteors burn up in this layer.

Thermosphere

Located above the mesosphere and extends to about 600 km (370 miles) above the ground.
Temperature increases with increasing altitude due to the absorption of solar radiation.

Exosphere

The outermost layer of the atmosphere.
Merges with outer space.
Temperature increases with increasing altitude, but the air is extremely thin.

Population Ecology

Studies how populations interact with their environment and with each other.

Levels of Organization in Ecology

Individuals

The basic unit of ecology.

Species

A group of organisms that can interbreed and produce fertile offspring.
Each species is given a two-part scientific name, called a binomial name (Latin for “two names”).

Population Level

A group of individuals of the same species living in the same geographic area at the same time.

Communities

All the populations of different species in a given area.
Focuses on how different species interact with each other.

Ecosystem Level

Includes all the populations and species within a given area, along with the physical environment (abiotic factors) and their interactions.

Population Distribution, Density, and Size

Population Distribution

The pattern of how individuals are distributed within a geographic area.
Can be uneven, with some areas being sparsely populated and others being densely populated.

Patterns of Distribution

How individuals are arranged in space within a habitat.
Useful for understanding species biology and ecology.

Dispersion

The spatial relationship among individuals within a habitat.
Several patterns are possible, depending on factors such as environmental conditions, species growth characteristics, and animal behaviour.

Uniform Dispersion

Individuals are spaced more or less evenly across a habitat.
Found in species that secrete toxins to inhibit the growth of nearby individuals or in animal species that establish territories.

Random Dispersion

Individuals are dispersed randomly, with no predictable pattern.
Found in species that are not influenced by strong environmental factors.

Clumped Dispersion

Individuals are clustered in groups.
The most common pattern of distribution in nature.
Found in species that depend on social interactions, patchy resources, or environmental factors.
