What are Physical Changes of Matter?• Physical Property-
1.A characteristic of a substance that can be observed and measured without changing the identity of the substance.
2. Use all your senses
I will be able to describe and identify physical and chemical properties of matter.
• Examples– Color – Size– Shape– Boiling point– Texture– Melting point– Mass– Magnetic attraction– Volume– Malleability– State of matter (solid, liquid,
gas)– Solubility– Electrical conductivity– Density

What are Physical Changes of Matter?Chemical Property-
1.Describes a substances ability to change into a new substance with different properties.
2.Some common chemical properties are:
a. Flammability – ability to burn
b. Reactivity – baking soda and vinegar
c. Rust - reacts with oxygend. Ripening of fruit
I will be able to describe and identify physical and chemical properties of matter.

What are Physical Changes of Matter?Physical Change:
1. A physical properties is changed from one form to another.
a. During a physical change the shape, size or appearance of an object may be altered.
b. The chemical make-up of the substance is not changed.
I will be able to describe the differences between chemical and physical changes of matter.

What are Physical Changes of Matter?Chemical Change:
1. Occur when one or more substances change into entirely new substances with different properties.
2. Chemical changes result in NEW substances, physical changes do not.
I will be able to describe the differences between chemical and physical changes of matter.
Signs that indicate a Chemical Change.1. Production of an odor2. Production of a gas
• Fizzing / foaming3. Changes in temperature
• Endothermic – absorbs heat (feels colder)
• Exothermic – gives off heat (feels hotter)
