Physical and Chemical Changes magnetism

Everything that has mass and volume is called matter. Everything is made of matter

Matter has properties o Two basic types of properties that we can associate with matter. n Physical properties n Chemical properties

h o o What are properties? Characteristics used to identify, describe and classify matter Two basic types of properties of matter are : Physical properties and Chemical properties:

Physical Properties o Characteristic of a substance that can be measured/observed (using your senses) without changing the substance into something else. size Texture color Odor Taste mass shape Volume Freezing/boiling melting point Magnetism density Temperature

More EXAMPLES - Physical o Physical State solid, liquid, gas or plasma Viscosity - The resistance of a liquid to flowing. n n n Examples: Low viscosity-water, rubbing alcohol High viscosity-honey

Chemical Properties o Chemical properties are characteristics involved when a substance interacts with another substance to change its chemical make-up. Flammability Rusting Creating a Reactivity with new chemical water product Creating gas bubbles p. H

Alike? Different? o Draw a double bubble map in your notes to compare and contrast physical and chemical properties.

Matter is everywhere. o Matter is anything that takes up space and has mass. o Matter is constantly experiencing both chemical and physical changes. o

Physical Change o o Physical changes occur when matter changes its physical property but not its chemical properties. No new substance is created. Physical property changes could include a change in: texture, shape, size, color, volume, mass, weight, and density.

Examples of Physical Changes o o o Boiling Freezing Dissolving Breaking Making a mixture n n n 2 or more types of matter (substances) mixed together Not in specific amounts Can be separated physically

Chemical Change Chemical changes are changes matter undergoes when it becomes new or different matter. o To identify a chemical change look for signs such as, bubbling and fizzing, light production, color change with an odor, smoke, and presence of heat. o

Evidence of a Chemical Change n n Formation of gas Formation of precipitate (a solid that results from two liquids reacting) Change in color Change in energy/change in Temp. o o Endothermic Absorbs heat energy (gets cold) Exothermic Releases heat energy (gets hot)

What kind of changes does matter undergo? The type of change that occurs in matter depends on the type of properties that are changed. Physical changes change physical properties only Chemical changes change chemical properties and physical properties

Chemical Changes o The composition of the substance changes. n The substances present at the beginning of the change are not present at the end; new substances are formed. The change cannot be “undone. ”
