States of Matter

Solids, Liquids, and Gases


What are the Characteristics of Solids?

  • A solid has a definite shape and definite volume.


How are particle in a solid arranged?

  • packed very closely together.

  • Tightly fixed in one position.

  • Ex. Wood, stone, and steel


Do particles in a solid move?

  • Yes.

  • The particles in a solid vibrate back and forth but stay in place.


There are Two types of Solids

Crystalline Solids

and

Amorphous Solids

Amorphous and Crystalline Solids


Crystalline Solids

  • In many solids, the particles form a regular, repeating pattern. These patterns create crystals. Solids that are made up of crystals are called crystalline solids.

  • Ex. Salt, sugar, and snow.

  • When a crystalline solid is heated, it melts at a specific temperature.


Amorphous Solids

  • Particles are not arranged in a regular pattern.

  • Ex. Plastics, rubber, butter, and glass.

  • Unlike crystalline solids, an amorphous solid does not melt at a distinct temperature. Instead, it may become softer and softer or change into other substances.


Solids

  • Eureka Solids


What are the Characteristics of Liquids?

  • Has a definite volume but no shape of its own. Without a container, a liquid spreads into a wide, shallow puddle.


How are particle in a liquid arranged?These particles move freely over each other and they are attracted to each other.


Do particles in a liquid move?

  • Yes.

  • The particles in a liquid are packed almost as closely as in a solid. However, the particles in a liquid move around one another freely.

  • Liquids vibrate, move about, and slide past each other

  • Liquids are also called fluids which means “a substance that flows”.

  • It has no definite shape.

  • It does have a definite volume.

  • Eureka Liquids


Properties of Liquids

  • There are two properties of liquids:

    Surface tension and Viscosity


Surface Tension

  • The result of an inward pull among the molecule of a liquid that bring the molecules on the surface close together.

  • Ex. Perhaps you have noticed that water forms droplets and can beads up on many surfaces, such as the water on your body after a shower.


Viscosity

  • A liquid’s resistance to flowing.

  • A liquid’s viscosity depends on the size and shape of its particles and the attractions between the particles.

  • A liquid with high viscosity flows slowly.

  • Ex. Honey and syrup.

  • A liquid with low viscosity flows quickly

  • Ex. Water and soda


What are the Characteristics of Gases?

  • Like liquids, gases are fluids. Unlike liquids, gas can change volume very easily. If you put a gas in a closed container the gas particles will either spread apart or be squeezed together as they fill the container.

  • Ex. Take a deep breath. Your lungs fills with air. Air is a mixture of gases. When you breath in, air takes the shape of your lungs. When you breath out, it does not have a definite shape.


How are particle in a gas arranged?Particles move freely and easily.


Do particles in a gas move?

  • Yes.

  • As gas moves, the particles spread apart, filling all the space available.

  • A gas does not have a definite shape or a definite volume.

  • Gas vibrates and moves freely at high speeds
