Vaporization is a physical change, not chemical.
Boiling is a physical change, not chemical.
Boiling water is physical change.
Yes, reactivity to vinegar is an example of a physical property because it describes how a substance behaves without altering its chemical composition. In this case, the reaction between vinegar and a substance demonstrates a physical change rather than a chemical one.
Elasticity is a physical property related to the ability of a material to deform and return to its original shape when a force is applied. It is not a change in the chemical composition of the material, so it is a physical property rather than a chemical change.
Although it has physical consequences, burning a log is a chemical change. The molecules of the log react with oxygen to form carbon dioxide, water steam, and many other products. A simple, fairly reliable test to tell the difference between physical and chemical changes is: Can the process be reversed rather easily? If the answer is yes, like dissolving salt in water, it is a physical change; if no, a chemical change.
Boiling is a physical change, not chemical.
Boiling is a physical change.
Boiling water is physical change.
Melting is a physical process.
A car crash is physical.
Carving a stone or molding a dough
Freezing/melting or evaporation/condensation, are physical changes that don't affect the chemical nature of the substances.
when a rock is erodded by wind or waves is a physical change where acid rain eroding a stone figure would be chemical
Which of the following is an example of a physical rather then a chemical change? Which of the following is an example of a physical rather then a chemical change?
Sawdust is not a change. Making solid wood into sawdust by sawing it, would be a physical change.
No. Antacids neutralize the hydrochloric acid in the stomach. It is a chemical change.
Weight is not an example of a physical change, but rather a physical property. A physical change involves altering the form or appearance of a substance without changing its chemical composition. Changing the weight of an object would involve chemical reactions or interactions, thus falling outside the definition of a physical change.
