States of matter

States of Matter

Solids, Liquids, and Gases


What are the characteristics of solids

What are the Characteristics of Solids?

  • A solid has a definite shape and definite volume.


How are particle in a solid arranged

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

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

There are Two types of Solids

Crystalline Solids

and

Amorphous Solids

Amorphous and Crystalline Solids


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

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

Solids

  • Eureka Solids


What are the characteristics of liquids

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.


States of matter

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

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

Properties of Liquids

  • There are two properties of liquids:

    Surface tension and Viscosity


Surface tension

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

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

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

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


Do particles in a gas move

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
