P AND C PROPERTIES VID

 observe whether a new substance is formedchemical composition, such as melting ice

Dua shehzad

A change is physical if it alters the appearance or form of a substance without changing its chemical composition, like melting ice or chopping wood. A change is chemical if it creates a new substance with different properties, such as burning wood or rusting iron.

Chemical Property:

I would recognize that this is a chemical property by observing how it behaves and observing that changes it makes and by looking at that it has changed it's form into another and makes a new material, is called a Chemical property.

EXAMPLES:

1. Corrosive

2. Toxic

3. Flammable

Physical property:

I would recognize that this is a physical property by telling what recognizing what material is this an physical properties can ONLY change it's shape and size.

EXAMPLES:

1. Ductile

2. Luster

3. Malleable

A change is physical if it alters the form or appearance of a substance without changing its chemical composition; it's chemical if it produces a new substance with different properties

observe for changes in the substance's composition or appearance.

Physical:melting ice

Chemical freezing water turn into solid water.

BY ZOYA & ABDULLAH

Examples of physical change: melting an ice cube, crumpling a paper bag, chopping wood, and boiling water

Examples of chemical change:Burning wood.

Souring milk.

Combining base and acid.

Digesting food.

A chemical change involves the formation of new substances with different properties, while a physical change alters the appearance or form of a substance without changing its chemical composition

if it's a chemical change it's irreversible and if paper burns it makes a new substance but physical change are reversible like boiling water

ameen

ANS1: Formation of a new substance (chemical), the release of heat, light, or sound (chemical), or changes in appearance without altering the substance's composition (physical).

ANS2:

Physical:Breaking a bottle

Chemical:Burning a paper

physical change : melting ice

chemical change : burning wood

oberserve for changes in the substances composition for apperance BY ASJAL X 『ᴅʀ』ㅤMᴀᴅᴀʀᴀ亗

If the change is a chemical change so a new substance will produced for example if paper is burned so ash will be produced and in physical change a new substance is not produced but it changes the shape for example if we hammer aluminium so it will change its shape so it is a physical change

n a physical change the appearance or form of the matter changes but the kind of matter in the substance does not.

Amash Ahmed

If the change is a chemical change so a new substance will produced for example if paper is burned so ash will be produced and in physical change a new substance is not produced but it changes the shape for example if we hammer aluminium so it will change its shape so it is a physical change.

Aahil Ali

ANS1: Formation of a new substance (chemical), the release of heat, light, or sound (chemical), or changes in appearance without altering the substance's composition (physical).

ANS2:

Physical:Breaking a bottle

Chemical:Burning a paper

Physical change:melting ice

Chemical change: Freezing water turn into solid water.

 hareem hussain

A change is physical if it alters the form or appearance of a substance without changing its chemical composition; it's chemical if it produces a new substance with different properties

Ans2:Physical change: Ice melting into water.

Chemical change: Iron rusting when exposed to air.

you can observe them by seeing how they behave and what are other points which can help you figure them out.

the chemical change is like

baking a cake and like cutting an apple is physical change these examples can help us figure out that what is physical change and what is chemical change

A physical change alters the form of a substance but not its identity. A chemical change creates a new substance.

Ayra

physical change cannot change substance it changes matter so we willl get to know about physical and chemical change

FILZA WAQAR

Ans1:Chemical Change: New substance forms with indicators like gas production (bubbles), color change, temperature change, odor formation, or precipitate formation.

Physical Change: No new substance forms; changes are reversible and involve state, shape, or size alterations

observe for changes in the substance's composition or appearance.

What clues help you figure out if a change is chemical or physical?

Give one example of physical change and one example of chemical change.
