Week1_Prompt#2
The diffrence between a chemical change and a physical change is pretty simple.A chemical change is when one or more substances are changed to a whole new substance.The easiest way i can describe a chemical change is by saying it's like this,if you mix orange juice with grape juice it taste like a completly different type of juice.A physical change is just when something looks differnt but is the same substance.Like ice for instance,if you see a cup of ice and a cup of water isn't it the same thing?Its the same exact substance it just appers diffrently.Which now leads me to matter physical apperence has alot to do with matter.Back to the ice ,the ice takes up more space than the melted water right? So as you can see the physical change or apperence has alot to do with the matter becauase every state takes up space.So to remember this chemical,physical and matter are all connected...

ReplyDeleteYou make good points supporting your explanation. You have an intro, a conclusion, and examples to support your answer. Remember that in a physical change the substance keeps it properties and in a chemical change the substances properties change. Also, you need to have resources! Overall, nice job!
