Study Notes

States of Matter

Solids, liquids, and gases are classified by their ability to change shape and volume.
Solids have a fixed shape and volume.
Liquids have a fixed volume but can change shape.
Gases can change both shape and volume.
All matter is made up of tiny, moving particles.
The particles in a substance are the same in its solid, liquid, and gaseous forms.
Particles in matter can be molecules, atoms, or a subunit of an atom.
Different states of matter have different levels of particle motion.
The particles in a substance have more motion in a gas than in a liquid, and more motion in a liquid than in a solid.
The rock and the flowing lava are made of the same kind of particles.
Kinetic energy is the energy of motion.
The particles in matter have kinetic energy.
The particles in matter are in constant motion (even in solids).
As particle motion increases, kinetic energy also increases.
Particles in solids are in a structured pattern and vibrate in place.
Particles in liquids can move past each other but maintain contact.

Gases

Particles are far apart and move rapidly, randomly, and in all directions.
Collisions between particles are infrequent due to the large distances between them.
Gases have high kinetic energy, meaning particles move quickly.
Particle attraction has minimal influence on their movement.

Liquids

Particles are close together but not rigidly arranged, allowing them to move past each other.
They experience stronger interparticle attraction than gases, influencing their movement and flow.
Liquids exhibit moderate kinetic energy, representing a balance between fast-moving particles and attractive forces.

Solids

Particles are tightly packed in a fixed arrangement.
Particles vibrate in their fixed positions due to strong interparticle attraction keeping them bound in a rigid structure.
Solids have the strongest interparticle attraction, holding particles in place and limiting their movement.
Solids have low kinetic energy, as particles have minimal motion.

Water's Unusual Density

Water's density pattern deviates from other substances, exhibiting an unusual characteristic where its solid state (ice) is less dense than its liquid state.
Ice molecules form a specific repeating pattern, creating open spaces between particles.
This spacing between particles in ice results in lower density than liquid water, causing ice to float.

Importance of Ice

Ice plays a crucial role in the Earth's system, impacting the hydrosphere, atmosphere, biosphere and providing habitats.
The hydrosphere, which includes oceans, lakes, and rivers, is largely covered by ice.
Ice interacts with the atmosphere, influencing weather patterns and global climate through processes like reflection of sunlight and storage of heat.
Ice provides habitats for numerous species, including penguins, polar bears, and walruses.
