Phases/States of matter


A change of state quick lab

A Change of State Quick Lab

Procedure:

Dip the cotton swab into the alcohol .

Make sure there are no cuts on your skin

Rub the Cotton swab on the palm of your hand

Questions (answer on your paper)

What happened when you put the alcohol on your hand?

What change of state occurred?

Did you sense hot or cold?

How did the alcohol particles’ movement change?

Phases/States of Matter

States of Matter = the physical forms of a substance. There are 4!

States of Matter depend on the motion of the particles

- Matter is made of atoms (tiny particles) and are always bumping into each other. The motion is different for each state.


Solid

Solid

Where do we see solids around us?

  • Solid is a state of matter in which the volume and shape of a substance are fixed.

  • The particles of a solid are closely locked in position and can only vibrate.


Liquid

Liquid

  • Liquid is a state of matter that has a definite volume but not a definite shape.

  • A liquid takes the shape of its container.

  • The particles of a liquid are able to slide past each other. A liquid’s particles are more loosely connected than those of a solid.

Where do we see liquids around us?

Gas

  • Gas is a state of matter that does not have a definite volume or shape.

  • The particles of a gas move about freely and collide randomly with each other.

Where do we find gases around us?

Plasma

Plasma

  • Plasma is a state of matter that starts as a gas and then becomes ionized.

  • Plasma consists of free-moving ions and electrons and can take on an electrical charge.

  • More than 99% of the matter in the universe is plasma. On Earth, natural plasmas are found in lightning and fire.

1. Solid, Liquid, Gas?

  • Gas

    • Particles are far apart

      • Moving randomly

      • Colliding

2. Solid, Liquid, Gas?

  • Solid

    • Definite shape and volume

    • Locked positions

    • Vibrating

3. Solid, Liquid, Gas?

  • Liquid

    • Packed almost as tightly as solid, but not as much

    • Particles able to slide and collide
