Physical and Chemical Properties

Chemical and Physical Changes n Set up part of your paper like so: Example

Chemical and Physical Changes n Set up part of your paper like so: Example Breaking Candy Boiling Water Baking Soda/Vinegar Burning Paper Melting Ice Physical Chemical

Physical and Chemical Properties of Matter Physical Properties Chemical Properties Definition characteristics that can

Physical and Chemical Properties of Matter Physical Properties Chemical Properties Definition characteristics that can be observed directly Example(s) Change in: color, odor, Change results in … characteristics that can only be observed when a substance changes into a different substance Rusted nail, fireworks texture, density, exploding, rotting brittleness, state (phase) bananas Different substance Same substance

Chemical and Physical Changes n Look back at your predictions… Example Physical Breaking Candy

Chemical and Physical Changes n Look back at your predictions… Example Physical Breaking Candy X Boiling Water X Chemical Baking Soda/Vinegar X Burning Paper X Melting Ice X

Measuring Properties n Quantitative Measurements – Properties that can be assigned numbers (ex. Mass,

Measuring Properties n Quantitative Measurements – Properties that can be assigned numbers (ex. Mass, length, density, volume) n Qualitative Measurements – Descriptions; things that are not measured in numbers (ex. Color, texture, etc…)

How can we measure properties in the lab? Property Length Volume Conductivity Texture Mass
