Are reversible changes and physical changes the same?
Reversible changes and physical changes are not exactly the same. Reversible changes can be undone and the original substance can be recovered, while physical changes alter the appearance or state of a substance without changing its chemical composition. Physical changes are usually reversible, but not all reversible changes are physical changes.
Is moss on a branch a physical or chemical change?
Moss growing on a branch is a biological process rather than a physical or chemical change. However, if you're considering the changes that occur during moss growth, it can involve both physical changes, such as the alteration of the branch's appearance, and chemical changes, such as the decomposition of organic material and nutrient absorption. Overall, the presence of moss indicates ecological change rather than a straightforward physical or chemical transformation.
Changes in properties of matter are called?
physical or chemical changes
What are phase changes?
its physical changes
Is it true that Physical changes are often accompanied by changes in color or odor.?
No. It is false. Physical changes are not accompanied by changes in color or odor.
When platinum is heated then cooled to its original state is a physical change?
Yes, heating platinum and cooling it back to its original state is a physical change. This process involves a change in the state of matter (from solid to liquid and back to solid) without altering the chemical composition of the platinum.
Historical evidence for the U.S. economy indicates that?
changes in real GDP over the business cycle are largely attributable to changes in investment over the business cycle.
What evidence do biologists use to establish evolutionary traits?
They use the physical changes in physical Form of an Organism, that naturally occur over Time, to do this.
What changes gives NO evidence that a chemical reaction has taken place?
Changes such as a change in state (solid to liquid), change in color, change in odor, change in solubility, or change in temperature do not provide direct evidence that a chemical reaction has occurred. These changes can be indicative of a physical change rather than a chemical change. To confirm a chemical reaction, additional evidence such as the formation of new substances, evolution of gas, or consumption of reactants is necessary.
Are state changes chemical or physical changes?
Physical Changes
What does the platinum orb do?
the platinum orb ( or in Pokemon platinum "the greiceus orb") this is given to giratina and then it changes to its original form.
What is marijuana physical changes?

Boils at 450 C a chemical or physical property?
Boiling point at 450°C is a physical property, specifically a characteristic of a substance that describes its behavior in response to changes in temperature. It is a fixed value for a specific substance and indicates the temperature at which the substance changes from liquid to gas at a specific pressure.
What are the chemical and physical changes of photosynthesis?
There are no physical changes. there are only chemical changes.
Are reversible changes and physical changes the same?
