A physical in size or state of matter. A example of physical change is cutting a strawberry.The cause of physical changes are temperature, pressure and motion.

Chemical changes include molecules in the matter change. It is often impossible to reverse chemical changes.When chemical changes gas forms light and heate appears and color can change too.]]> 2018-03-27 14:33:20 UTC https://padlet.com/scott_grieve26/PC/wish/246520167 scott_grieve26 https://padlet.com/scott_grieve26/PC/wish/246520178 Physical change can change without changing the substance but a chemical change forms a new substance when the moleculis or matter change. Example of a physical change is copper melted water frozen into an icecube 
Straw berry cut in half. Glass broken in half or paper ripped in half and wood cut in halfnow here are some chemical changes wood set on fire turns in to ash. Paper set on fire turns into ash as well.

A Chemical change is a change of substance . A example of a Physical change is when a ice cube melts. An example of a Chemical change is when you bake a cake . ]]> 2018-03-27 14:33:36 UTC https://padlet.com/scott_grieve26/PC/wish/246520344 https://padlet.com/scott_grieve26/PC/wish/246520646 - Physical change can be reversed but chemical change cannot be reversed.
- Physical change does not form new substance however chemical change does form a new substance
- Physical change = a change in the size or state of matter.
- Chemical change = when the molecules of the matter change and chemicals change usually cannot be reversed
- Physical change can be caused by motion, pressure, and temperature.
- Clues for Chemical change gas forms and light or heat appears
EXAMPLES OF PHYSICAL CHANGE: 
-When you rip a piece of paper it has gone through physical change. Also the paper did not change, it is still one substance.
EXAMPLES OF CHEMICAL CHANGE:
- When you heat pancake batter it becomes into a pancake and there is no way to reverse it.

A Physical Change is when something changes shape without substance . Also, when matter changes state, it goes through physical state.
eg. you have a ice cream cone that is frozen and the ice cream melts and cannot be reformed again. That is called Physical Change. ]]> 2018-03-27 14:37:06 UTC https://padlet.com/scott_grieve26/PC/wish/246522548 https://padlet.com/scott_grieve26/PC/wish/246523530 A physical change includes bending, cutting, tearing, and changing the state of matter.(e.g   if you tear a piece of paper, its a physical change because it remains paper, no new substance is formed but if you burn paper, then it will turn into ashes forming a new substance which means its a chemical change.) A chemical change is when the molecules in matter change and form a new substance. Here is a link to a video that describes the difference between physical and chemical changes.

_For example,if you rip a piece of paper,that piece of paper went trough phyisical change
_If something broke,the object is still the same
