Is rotten food an example of physical change?
No, rotten food is not an example of a physical change; it is a chemical change. During the process of decomposition, the food undergoes chemical reactions that alter its composition, leading to the development of new substances and the breakdown of original ones. Physical changes, on the other hand, involve alterations in state or appearance without changing the chemical identity of the material.
What is the composition of the materials during physical change?
During a physical change, the composition of the materials remains the same. The change only affects the physical properties of the substance, such as its shape, size, or state of matter, without altering its chemical composition. This means that no new substances are formed during a physical change.
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.
Can new compounds form during a physical change?
no because in a physical change it does not change the chemical make up, however, it does during a chemical change
A physical change to a slice of tomato is letting it rot?
Letting a slice of tomato rot is primarily a chemical change rather than a physical change. During the rotting process, the organic compounds in the tomato undergo decomposition due to microbial activity, resulting in new substances and changes in texture, color, and smell. While the physical appearance of the tomato changes, the underlying chemical composition is altered, making it a chemical transformation.
How does temperature change during change of physical change?
Temperature remains constant during the change in phase (physical state).
Is rotten food an example of physical change?
No, rotten food is not an example of a physical change; it is a chemical change.

Do substance like molecules change during a physical change?
No the substances like molecules donot chane during physical change .

Is heating sand to its melting point a chemical or physical change?
Heating is purely physical, though at higher temperatures also some or many chemical reactions might take place: e.g. decomposition (break down) of mineral carbonates into oxides and carbon dioxide.

What phase is skipped during deposition?
liquid
Is painting a door a physical or chemical change?
Physical change of the paint, not the door.
Is wood and leaves rot to form humus a physical or chemical change?
a chemical change
What does physical and chemical mean in science?
Chemical change: the composition of the initial reactants is changed. Ex.: thermal decomposition of calcium carbonate. Physical change: the composition is not changed during this transformation. Ex.: boiling of water.
