In A Physical Change, One Or More Physical Properties Of A Substance Are Altered.
A chemical change is when bonds are broken and new ones are forced to form. Chemical changes involve the formation of a new substance. Matter is capable of undergoing changes, which are classified as either physical or chemical.
Explore The Difference Between Physical Change And Chemical Change By Performing An Experiment.
Lab physical and chemical changes assignment lab report. You will observe that energy must be used to start some chemical reactions, and that it is produced in others. Chemistry is the study of matter and the changes it undergoes.
In This Lab Exercise You Will Observe Various Physical And Chemical Changes And Note The Differences Between These Types Of Changes.
You will also use some Physical changes usually involve a change to a substances state of matter where heat energy is added or removed. These changes can be divided into 2 classes:
A Log Burned In A Fire Turns To Ashes, But The Ashes Cannot Be Changed Back.
The new substance will have a different composition and also different properties than the original substance. In this lab, materials such as calcium carbonate, water, iron filings and sulfur, among others were used to investigate a type of change and the reasoning for the change. You will also make qualitative observations and use them to determine if experiments are examples of physical or chemical changes.
