Do Now 9-1-16 Properties of Matter Chemical and Physical Properties What is Matter? Matter is: anything that has mass and takes up space. Chemistry is: the study of matter and how it changes. https://youtu.be/uJOGy0 dgmUU Physical Properties • Can be observed or measured without changing the composition of a substance • Use your senses to observe some of the basic physical properties of a substance • Describe the appearance of matter. Physical Properties Examples: shape color odor texture melting point boiling point strength hardness conductivity magnetism Physical Properties Other Examples: heat viscosity density buoyancy state of matter Chemical Properties • Chemical property: the way a substance reacts with others to form new substances with different properties • Describes the behavior or reactivity of matter. Chemical Properties Examples: Reactivity Flammability Corrosion Tarnishing pH Physical or Chemical Property? Determine in the next slides if it is a physical property or chemical property. Water boils at 100 degrees Celsius Diamonds are capable of cutting glass Water can be separated into hydrogen and oxygen Sugar is capable of dissolving in water Vinegar will react with baking soda Yeast acts on sugar to form carbon dioxide and ethanol Wood is flammable Aluminum has a low density Ammonia is a gas at room temperature Bromine has a red color Questions
