it does not change .
chemical changes are those change and cannot come back again 
w - is there any types that last year was not thought]]> 2021-06-16 08:16:32 UTC https://padlet.com/smescience/vdffniv8y9exsuob/wish/1609524072 https://padlet.com/smescience/vdffniv8y9exsuob/wish/1609524122 Know - the characteristics and examples of physical and chemical changes
Want to know - The exceptions in the examples of these changes]]> 2021-06-16 08:16:34 UTC https://padlet.com/smescience/vdffniv8y9exsuob/wish/1609524122 https://padlet.com/smescience/vdffniv8y9exsuob/wish/1609524192 What i know?
- How chemical reactions happen
- How to differentiate between chemical and physicals changes
- Revisable and non-Revisable changes

What i wanna know?
- EVRYTHING!!!]]> 2021-06-16 08:16:38 UTC https://padlet.com/smescience/vdffniv8y9exsuob/wish/1609524192 https://padlet.com/smescience/vdffniv8y9exsuob/wish/1609524263 K-The changes in which the chemical composition is not altered is called physical change. It is MOST LIKELY to be reversible.eg-melting of ice. Chemical change is the change in which the chemical composition is altered. It is irreversible.eg-burning of wood.

wk- i want to know is there any change like colour,texture, etc changes in physical change.]]> 2021-06-16 08:16:45 UTC https://padlet.com/smescience/vdffniv8y9exsuob/wish/1609524319 https://padlet.com/smescience/vdffniv8y9exsuob/wish/1609524703 K - Physical changes are does changes which are temporary and reversible .example = boiling of water melting of ice 
Chemical changes are permanent and irreversible.example  burning of candle etc
W  - whatever is left to learn for physical and chemical changes

Chemical changes are changes which happen in the structure gif the matter  . They are generally not reversible and  huge amount of energy is released during chemical change

= physicals change can be reversible 
= chemical changes can not be reversed
 What I what to known:
= more properties of both chemical and physical changes]]> 2021-06-16 08:17:21 UTC https://padlet.com/smescience/vdffniv8y9exsuob/wish/1609525082 https://padlet.com/smescience/vdffniv8y9exsuob/wish/1609525187 K- physical changes are reversible and do not change the chemical characteristics of a substance
K-chemical changes are irreversible and do change the chemical characteristics of a substance]]> 2021-06-16 08:17:26 UTC https://padlet.com/smescience/vdffniv8y9exsuob/wish/1609525187 https://padlet.com/smescience/vdffniv8y9exsuob/wish/1609525853 K- Physical change does not change the compostion of its molecule.
Chemical change changes the composition of its molecules.
There are many daily life examples of these changes..]]> 2021-06-16 08:17:56 UTC https://padlet.com/smescience/vdffniv8y9exsuob/wish/1609525853 https://padlet.com/smescience/vdffniv8y9exsuob/wish/1609526174 k-physical change is a change which can come back...
chemical change is a change which can never come back...]]> 2021-06-16 08:18:11 UTC https://padlet.com/smescience/vdffniv8y9exsuob/wish/1609526174 https://padlet.com/smescience/vdffniv8y9exsuob/wish/1609526238 K-physical changes are the changes that when happens there is no change in state or molecules in the reactent and it is a reversible change
Chemical changes are the changes that when takes place the chemical property,molecular property and is irreversable change

- chemical changes are irreversible changes

W- chemical reactions with different substances ]]> 2021-06-16 08:18:56 UTC https://padlet.com/smescience/vdffniv8y9exsuob/wish/1609527160 https://padlet.com/smescience/vdffniv8y9exsuob/wish/1609527963 what i know:-
physical change are changes affecting the form of the substance/appearance but not its chemical composition.

chemical chnage:-
chemical change occur when a substance combines with another to form a new substance unlike physical change chemical change changes in chemical composition as well

what i want to know:-

how to differentiate when an object show both chemical and physical change]]> 2021-06-16 08:19:30 UTC https://padlet.com/smescience/vdffniv8y9exsuob/wish/1609527963 https://padlet.com/smescience/vdffniv8y9exsuob/wish/1609529310 K- Physical change
Can be reversed 
No new thing is formed 
Just change the state 
Ex. Ice melting 

Chemical change:
Cannot be reversible 
New thing is formed 
Ex. Boiling of egg. 





W- I want to know if blood is exactly physical and chemical change 

Any properties which are not known yet

K - in physical changes there is no new substance formed . Something they are reversible 
In Chemical change there is a change in its chemical properties . It is a permanent change
