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 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 what a chemical change is?
A chemical change is when a substance undergoes a transformation that results in the formation of one or more new substances with different chemical properties. This typically involves the breaking and forming of chemical bonds between atoms. Examples of chemical changes include rusting of iron and burning of wood.
When a physical change take place explain why?
A physical change occurs when a substance alters its form or appearance without changing its chemical composition. This can happen due to factors like temperature, pressure, or the addition of energy, such as when ice melts into water. During a physical change, the molecular structure remains intact; only the arrangement or state of the molecules is affected. Examples include changes in state (solid, liquid, gas) and changes in shape or size.
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 twisting a wire chemical or physical change explain?
It is physical. The wire changes shape, but it is still made of the same materials.

Need help on science homework has anyone answered this question Are the changes from a to b and from b to c physical or chemical changes explain your answer?
The changes from A to B and from B to C are physical changes. Physical changes do not alter the chemical composition of the substances involved. In this case, the changes are likely related to states of matter or physical appearance, rather than chemical composition.
Is melting ice a chemical or physical change explain?

Explain Why physical changes can be reversed but chemical changes cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
Can you explain the difference between physical changes and chemical changes?
Physical changes is change in property. Ex) change from solid to liquid....ice to water. Chemical change changes to different substances. Ex) rotting of fruit.
Can matter undergo changes in both its physical and its chemical properties Explain please?
Yes, matter can undergo changes in both its physical and chemical properties. Physical changes involve alterations in the form or state of matter without changing its chemical composition, such as melting ice into water. Chemical changes, on the other hand, involve transformations at the molecular level, resulting in the formation of new substances with different chemical properties, such as rusting of iron.
What happens to mass during chemical and physical changes. explain?
Law of Conservation of Mass: mass can not be created or destroyed, it can only be changed (transformed).
What does matter mean in science 5 answers?
What does it mean for matter to change state?Hi,What Does Changing States Of Matter Mean? Can You Please Tell Me All The Answer Very Quickly Need The Definitions For Matter, Melting, Evaporation, Sublimation, Condensation And Freezing. Explain Physical Changes And Chemical Changes With Examples.
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.
Did the Greeks explain why chemical changes occurred?
