what are 5 physical changes and 5 chemical changes Q1 How can you tell the difference between physical and chemical changes The appearance or form of matter changes during a physical change but the type of matter in the substance does not A chemical change on the other contrary results in the creation of at least one new substance with new properties Q2

Matter is capable of undergoing changes which are classified as either physical or chemical Physical changes in matter are often reversible An ice cube can melt into liquid water and then the liquid water can be frozen back into an ice cube Chemical changes on the other hand are not reversible A log burned in a fire turns to ashes but Label each of the following changes as a physical or chemical change A mirror is broken An iron nail corroded in moist air Copper metal is melted A catalytic converter changes nitrogen dioxide to nitrogen gas and oxygen gas Answer a physical change Answer b chemical change Answer c physical change Answer d chemical change

Any change in these physical properties is referred to as a physical change For further information please refer to Properties of Matter Chemical changes on the other hand are quite different A chemical change occurs when the substance s composition is changed When bonds are broken and new ones are formed a chemical change occurs Matter is capable of undergoing changes which are classified as either physical or chemical Physical changes in matter are often reversible For example an ice cube can melt into liquid water and then the liquid water can be refrozen into an ice cube A chemical change is very different A burning log demonstrates this

Physical changes are when just the structure of the matter changes but not the chemicals Chemical changes are when the identity of the chemicals change where we get new chemical with different properties Physical and chemical processes can be classified by the changes occurring on the molecular level In general chemical processes involve changes in chemical bonds while physical processes involve changes only in intermolecular forces Created by Sal Khan

A physical change is a change in matter that alters its form but not its chemical identity The size or shape of matter often changes but there is no chemical reaction Phase changes are physical changes These include melting boiling vaporization freezing sublimation and deposition What Is a Chemical Change Chemical changes are different from physical changes During a chemical change the molecules of a material do change The material becomes something new and different That is because its chemical bonds are broken and the atoms get rearranged Chemical bonds hold molecules together

Here are physical change examples along with a look at how to tell a physical change from a chemical change How to Identify a Physical Change Physical changes involve changes in physical properties Certain processes result in physical changes Phase transitions Melting freezing evaporation and sublimation are all Chemists make a distinction between two different types of changes that they study physical changes and chemical changes Physical changes are changes that do not alter the identity of a substance Chemical changes are changes that occur when one substance is turned into another substance Chemical changes are frequently harder
