What are physical properties of matter?
A characteristic of a substance that can be observed without changing the identity of the substance is called a physical property.
All of the senses can be used to observe physical properties: Color, shape, size, etc…
Active Reading #5
No: You can see an object's color or measure an object’s volume without changing the object’s identity.

Unit 1 Lesson 2 Properties of Matter
What are physical properties of matter?
Mass, volume and Density are physical properties.
Changing the mass or volume of a substance does not change the substance’s identity.

6. What are physical properties of matter?
Unit 1 Lesson 2 Properties of Matter
What are physical properties of matter?
The state of matter is a physical property. The state of matter is the physical form of the matter.
Most matter exists as a solid, liquid, or gas.
Visualize It #6
Gold: liquid/solid, yellow in color, ability to be shaped.
Table: round, large, solid

What are physical properties of matter?
Electrical conductivity is a measure of how well electric currents move through a substance.
Thermal conductivity is the rate at which a substance transfers heat.
Density is the measure of the amount of mas in a given amount of volume
#8 Explain
The vinegar is more dense than the oil

Unit 1 Lesson 2 Properties of Matter
What are physical properties of matter?
Solubility is the ability of a substance to dissolve in another substance.
Malleability is the ability of a substance to be rolled or pounded into various shapes.
Magnetic attraction is also a physical property that can be observed when metal attracts another metal
#9 Predict
Solubility is a physical property, the solid particles of the drink would be left behind. Their identity does not change
#10 Identify

9. What are physical properties of matter?
Unit 1 Lesson 2 Properties of Matter
What are physical properties of matter?
The melting point of a substance is the temperature at which it changes from a solid to a liquid.
The shine, or luster, of a metal can be easily observed. How it reflects light
The boiling point of a substance is the point at which the substance boils.
#11 Infer
Both the geyser’s eruption and the tea kettle’s whistle are caused by water vapor. As water boils, vapor escapes though a hole

What are chemical properties of matter?
A chemical property describes the ability of a substance to change into a new substance with different properties.
The ability to rust or tarnish is a chemical property. When a metal rusts or tarnishes, it changes to a different substance.

12. What are chemical properties of matter?
Unit 1 Lesson 2 Properties of Matter
What are chemical properties of matter?
Chemical properties can be identified by the changes they produce.
Flammability is the ability of a substance to burn.
Reactivity is the ability of a substance to interact with another substance and form one or more new substances.

13. Ability to change the identity and form a new substance
Chemical Properties
Ability to rust
Ability to tarnish

What is the difference between
physical and chemical properties?
Physical properties can be observed without changing the identity of a substance.
Chemical properties can be observed only by changing the identity of a substance.
Active Reading #14
Physical Property can be seen without changing the identify of the matter.
Chemical Property has the ability to change the substance.
Visualize it #15
The left nail shows the physical property of malleability
The right nail shows the chemical property of reactivity

What is the difference between
physical and chemical properties?
Properties unique to a substance are its characteristic properties.
Characteristic properties stay the same regardless of the amount of the sample. (Density)
Characteristic properties can be physical properties or chemical properties.
