Alternate Wordings for 'What is chemical change and physical change and give its examples?
Explain the difference between chemical change and physical change, and provide examples of each. Define chemical change and physical change, and provide examples to illustrate. Differentiate between chemical change and physical change, and give examples to clarify the distinction.
Is chemical change a temporary change Explain?
No, a chemical change is not a temporary change; it is usually permanent. During a chemical change, the substances involved undergo a transformation that alters their molecular structure, resulting in new substances with different properties. Unlike physical changes, which can often be reversed, chemical changes typically cannot be undone without undergoing another chemical reaction.
Is melting ice a chemical or physical change explain?
It is a physical change because when you have a chemical change it changes the properties and makes it into a new thing, and it can't be reversed. Physical changes are usually just changes of states (solid, liquid, gas) and a physical change can be reversed.
Explain why sublimation is regarded as a physical change but the slaking of lime is considered as a chemical change?
- Sublimation don't change the molecule; solid iodine or sublimated iodine are iodine. - Slaking of lime transform the calcium oxide in calcium hydroxide. A chemical change occur.
Is it a chemical or physical change when heat is put over sugar?
its physical change.to explain,the conversion of solid to liquid is physical
Explain how wood burning in a fire place undergoes a chemical change?
Burning is an oxydation reaction so a chemical change.
Explain why burning butter is a chemical change but melting is not?
Melting: change of phase, a physical phenomenon without change of the composition. Burning: a reaction of oxydation, a change of composition - a chemical change.
Is evidence of a chemical change?
Explain how a mixture of sand and salt can be separated.
Is twisting a wire chemical or physical change explain?
It is physical. The wire changes shape, but it is still made of the same materials.
In a candle explain both changes using the big idea of energy?
When a candle is burnt a physical AND chemical change takes place. Its a physical change when the wax is being melted because the chemical structure has not change, meaning it cannot be a chemical change. Its also a chemical change because you are burning the string. When you burn something the chemical structure DOES change, meaning it is a chemical change.
When the banana, berries, water, and hot dog are blended, does a physical or chemical change occur?
both physical and chemical change occur

How can you change the rate of chemical change in a substance?
This is a very vague question and would depend on the chemical that you are talking about. The easiest way I can think to explain it on a wide variety of chemicals is by using a catalyst (speeds up the process of a chemical reaction), or the use of an antagonist (Slows a chemical reaction). I hope this helps, but without any specific chemicals being named this is the best i can do. :) By heating we can change the rate of chemical change(reaction).
