Text z Príbehu
It is getting dark and cold. We need to get some wood and chop it up. I wonder what type of a change that it?
Since we are only changing the appearance of the wood by chopping it up then it is a physical change.
Our campfire wood is burning, can you tell me what kind of change that is?
Since the ashes can't go back to become wood then it is a chemical change.
OH no! I burned the marshmallow and now I can't eat it. Can you tell me what kind of change that is?
Since the marshmallow has burned and it it can not be reverse it to unburned state, then you know it is a chemical change.
Since you have helped me put up the tent do you know what kind of change that is?
I believe it is a physical change because no new substance was created and the change is reversable
What an amazing camping site! Will you help me understand the difference between physical and chemical changes during this trip?
I could not agree more. I will absolutely help you understand the difference between physical and chemical changes.
This is a beautiful ocean view, I wonder where our camp site is?
Looks like it is down the road. I think I see it.
