Properties of Matter Flashcards
Describe Physical Properties
Are properties that can be observed or measured without changing the identity of the matter.
Describe CHemical change
Are the process by which substances actually change into new substances.
How to identify chemical changes
Looking for key words:
- is producing heat
- is changing color
- is bubbling
- is letting off gases
- is burning
- is producing light
- is reacting with
- is combining with
- is bonding with
Describe reactivity
the ability of two or more substances to chemically bond or combine and form one or more new or different substances with new or different properties
Describe Density
the amount of matter in a given space of volume
Describe solubility
the ability to dissolve into another substance
Describe ductility
the ability to be drawn into a wire
Describe malleability
the ability to be pounded into thin sheets
Describe matter
anything that has mass and volume ( takes up space )
What is matter made up of?
atoms- tiny particles
Describe weight
a measure of the gravitational force on an object
List some physical properties
- Texture
- Oder
- Density
- Ductility
- Conductivity
- Shape
- Volume
- State ( solid, liquid, gas )
- Magnetism
- Mass
- Malleability
- Solubility
- Color
- Weight
How to identify chemical properties
- can produce heat
- will change color (that didn’t exist in the beginning)
- will bubble or fizz
- will let off gases
- can burn/produce heat
- will react
Describe Physical Changes
a change of matter that affects one or more physical properties of a substance
Describe chemical properties
describes matter based on its ability to change into new substances or matter that has new and/or different properties
