Water
Definite volume but takes the shape of its container
Helium
No definite shape or volume

19. Important Temperatures
Melting Point: The temperature when a solid becomes a liquid.
Boiling Point: The temperature when a liquid becomes a gas.
Freezing Point: The temperature when a liquid becomes a solid.
Condensation Point: The temperature when a gas becomes a liquid.

20. State

21. Clarity The ability for light to pass through matter
Definition:
The ability for light to pass through matter
Transparent: all light passes through
Translucent: some light passes through
Opaque: no light passes through

22. Luster The ability to reflect light Shiny: more reflection
Definition:
The ability to reflect light
Shiny: more reflection
Dull: less reflection

23. Form The structure in the matter
Definition:
The structure in the matter
Regular: patterned, cellular, crystalline
Irregular – no pattern

24. Texture Rough - Describing the surface of the matter Smooth - Sharp -
Definition:
Describing the surface of the matter
Examples of textures:
Rough -
Smooth -
Sharp -
Soft -

Bumpy -

25. Brittleness The ability to break or shatter easily Definition:
Example:

26. Thermal Conductivity
Definition:
The ability to transfer thermal energy (heat) to something else
Example:
Coffee in a special cup to prevent heat transfer to our hands

27. Electrical Conductivity
Definition:
The ability to conduct electricity (the atoms allow their electron to move or flow)
Example:
Metals and non metals
Conductors – good conductivity
Insulators – no conductivity

28. Viscosity The ability for matter to flow Viscous and non- viscous
Definition:
The ability for matter to flow
Example:
Viscous and non- viscous
Syrup, oil, water all have different viscosities (ml/s)

41. Types of Properties
Physical: properties that can be observed without changing the IDENTITY of the matter
A physical property is a property or characteristic of and object or substance that can be observed, described, and measured without changing the matter.
Chemical: property of a substance that changes it into a NEW substance (changes the identity of the substance)
