Properties of Matter Properties of matter describe matter. Example might be its color, hardness, shape, etc. Properties of matter describe matter. Example might be its color, hardness, shape, etc. What properties can you think of to describe matter? What properties can you think of to describe matter? All matter can change properties. For example Water can go from ice, to liquid form, and then to steam or water vapor. All matter can change properties. For example Water can go from ice, to liquid form, and then to steam or water vapor.

Characteristic Properties Characteristic Properties are those properties that hold true for a particular kind of substance or element and they never change. This is why they are great to use to identify substance, such as sulfur (think smell and color). Characteristic Properties are those properties that hold true for a particular kind of substance or element and they never change. This is why they are great to use to identify substance, such as sulfur (think smell and color). Example would be diamonds, which are made from the element Carbon. All diamonds share the characteristic property of being one of the hardest substances we know of. Example would be diamonds, which are made from the element Carbon. All diamonds share the characteristic property of being one of the hardest substances we know of.

Characteristic Properties Boiling Point Boiling point is what temperature a liquid boils at. Boiling point is what temperature a liquid boils at. Each liquid has a certain boiling point, thus this characteristic is used to help identify different liquids. Each liquid has a certain boiling point, thus this characteristic is used to help identify different liquids. Example would be water that boils at 100 degree Celsius. Example would be water that boils at 100 degree Celsius. Melting Point Melting Point is the temperature at which a solid will melt. Each solid has a certain melting point, thus this characteristic is used to help identify different solids. Example would be ice melts at 0 degree Celsius Many substance share similar characteristics such as boiling point, melting point, color, etc… Thus, usually you need to look at more than one characteristic property to accurately identify a substance.

Changes in Matter Physical Changes Physical changes alter the form of a substance, but doesn’t change it identity or what it is. Physical changes alter the form of a substance, but doesn’t change it identity or what it is. Example of Physical Change is water from ice to liquid to water vapor or steam. Water still holds its identity as water, but has a different form. Example of Physical Change is water from ice to liquid to water vapor or steam. Water still holds its identity as water, but has a different form. Boiling or melting are examples of physical change. Boiling or melting are examples of physical change. Can you think of other examples of physical change? Can you think of other examples of physical change? Chemical Changes In a chemical change one or more substance breaks apart or combines to form a new substance. This is what happens when a chemical compound is formed. Heat a lot of the time is involved with chemical changes. Two example of chemical change would be wood burning and Iron reacting with the Oxygen and Water in the air producing rust.

Solid Solid has a definite volume (the amount of space that matter occupies) and a definite shape. Solid has a definite volume (the amount of space that matter occupies) and a definite shape. This is because the particles in a solid are packed tightly together and stay in fixed positions. This is because the particles in a solid are packed tightly together and stay in fixed positions. Two types of Solids: Crystalline Solids and amorphous solid. Two types of Solids: Crystalline Solids and amorphous solid.

Solid Two types of Solids: Crystalline Solids and amorphous solid. Crystalline Solid Crystalline Solids have a regular repeating pattern, which form crystals. Crystalline Solids have a regular repeating pattern, which form crystals. Example would by salt, sugar, snow, etc… Example would by salt, sugar, snow, etc… Has a distinct, characteristic melting point. Has a distinct, characteristic melting point. Amorphous Solid Amorphous Solids have no regular pattern. Examples would be plastic, rubber, glass, etc… Doesn’t have a melting point, the solid just becomes softer and softer.

Liquid Liquid had no shape and takes on the shape of its container. Liquid had no shape and takes on the shape of its container. The reason for no shape is the particles are free to move, however it does have a definite volume. The reason for no shape is the particles are free to move, however it does have a definite volume. Liquids don’t like to compress meaning their volume doesn’t change even though their shape might. Liquids don’t like to compress meaning their volume doesn’t change even though their shape might. Particles in a liquid are free to move around, this is called fluid. Particles in a liquid are free to move around, this is called fluid. The resistance of the particles to flow is called viscosity. Thus a liquid is said to have high viscosity when it doesn’t flow or move very fast and said to have low viscosity when it flows fast. You use this word with describing volcanic lavas.

Gas Gas can change volume and has no definite shape. Gas can change volume and has no definite shape. Thus volume and shape of a container is the volume and shape of a gas. Thus volume and shape of a container is the volume and shape of a gas. Gas particles spread apart, filling the space available to them. Gas particles spread apart, filling the space available to them.
