Give two examples of The irrevesible change if Spammers they fuc...​

Answer 1

Answer:

An irreversible change is when something cannot be changed back to its original form. In many irreversible changes, new materials and substances are formed.  

Examples of Irreversible Changes

Burning - Once something is burnt, it can't be reverted back to its original form. It can't become unburnt. Once a piece of paper has been burnt, it can't be used to write or read anymore.

Cooking - Cooking changes the chemical composition of a substance. Once eggs or meat become cooked, it will never be raw again. Once a cake is baked it won't ever become milk and flour again.

Rusting - Once Iron is rusted, it cannot become unrusted. The rusted part can be sanded off and the underside can be re-shined, but if this continues, the iron will eventually thin out.  

Mixing - Mixing some substances together can cause an irreversible change to create a new substance. For example, cement, or vinegar and bicarbonate of soda to create carbon dioxide.
