Physical verse Chemical
Is there evan a difference between physical and chemical?
What are Examples of Properties?
There are many examples of properties all around you such as taste, which is the sensation of flavor perceived in the mouth and throat on contact with a substance. There is also volume and matter. Mass is the amount of matter in an object, and volume is the amount of space occupied by an object. Two other examples of properties are flammability and stability. Flammability is ability of a substance to burn or ignite, causing fire or combustion and stability is the state of being stable. Now that you know all of these different examples of properties do you know which are physical and which are chemical? If not thats okay, keep reading to see what the difference is between physical and chemical properties.
Physical Property of Matter
There are two types of properties, physical and chemical. A physical property is a characteristic of a substance that can be observed or measured without changing the matters identity or properties that can be looked at without changing the matter. Matter is anything that has mass and takes up space. One example of a physical property is color which is the property possessed by an object of producing different sensations on the eye as a result of the way the object reflects or emits light. Other examples are texture and shape. Texture is the feel, appearance, or consistency of a surface or a substance and shape is the outline of an area or figure.
Color
Color is an example of a physical property.
Texture
Texture is an example of a physical property.
Shape
Shape is an example of a physical property.
Whats a Physical Change in Matter?
When a physical change occurs no new substance is created and the original matter can still be recovered. The matters composition doesn't change and the original matter is still present. Even though the substance may look different the matter the atoms are linked up the same way. The physical form is changed without changing the chemical identity. An example of a physical change is mixing koolaid. The color of the substance changes and the taste but the chemical makeup is still the same. Another example is Drying clothes in the dryer. The texture changes but once agin not the chemical makeup. One more example is chopping wood. The shape changes but not the chemical makeup.
Water
Kool-Aid Mix
The two mixed
When the water and kool-aid are mixed together it is an example of a physical change. The color and taste may change but the chemical makeup is still the same.
Un-Chopped Wood
Chopping the Wood
Chopped Wood
This is an example of a physical change. The texture is different but the chemical makeup is still the same.
Chemical Properties of Matter
A chemical property of matter is a property of matter based on its abilities to change into different properties, it tells how matter reacts with other matter. Examples of chemical properties are flammability, acidity, and stability. Flammability is the ability of a substance to burn or ignite, causing fire or combustion. Acidity is the level of acid in substances such as water, and stability is the state of being stable.
Flammability
Flammability is an example of a chemical property.
Reactivity
Reactivity is an example of a chemical property.
Sensitivity to Light
Sensitivity to light is an example of a chemical property.
Whats a Chemical Change in Matter?
A chemical change in matter happens when one or more substances are changed into new substances that have new and different properties, the chemical identity of a substance is destroyed and a new substance is formed. Examples of chemical changes are fruit rotting, food spoiling, baking bread, burning wood, and much more. Unlike in a physical change, the chemical identity is changed and a new substance is created. The substance can not be turned back.
Un-Rotted Fruit
Fruit in the Process of Rotting
Completely Rotted Fruit
The fruit has completely rotted, the chemical makeup has totally changed. This is an example of a chemical change.
Bread Batter
Bread Baking
Completely Baked Bread
The bread had baked and the and the chemical makeup has totally changed. This is an example of a chemical change.
So How can I Tell Which is Which?
The basic difference between physical and chemical properties is a physical property can be measured or observed without changing the material and can be changed back to the original form. A chemical property can't be observed or measured without changing the chemical makeup and cannot be returned back to normal. The difference between physical change and chemical change is physical change doesn't change the actual makeup of the substance and chemical change changes the actual makeup of the substance. When it come down to decide which type of change and which type of property, you can answer your question by asking one question. Can my substance be changed back and is the chemical makeup the same? If your answer is yes then you are looking at a physical aspect if not, you are looking at a chemical aspect.
