Chemical vs. Physcial Change

Using complete sentences tell me the differences between chemical change and a physical change in science.  Also tell me the 4 states of matter.

The difference between chemical and physical change is that a physical change can be seperated from a substance, and a chemical change is when you can't seperate something between a substance. The four states of matter are gas, solid, liquid, and plazma.

A Chemical change changes the identity of the substance. A physical changes doesn't change the identity. SOLID,LIQUID,GAS,PLAZMA

A chemical change is if something changes what it is. Physical change is something that is still the sameof the whatever it is. The four types of the state of matter is Solid,Liquid, Gas, and Plasma.

The difference is that in a chemical change you can't undo it. For example if you put a flavor packet in a bottle of water you can't take take the flavor packet out. But in the physical property you can. The four states of matter are solid, liquid, gas and plasma

With physical change it doesn't change a objct's identidy. Chemical change changes a object's identidy. The 4 states of mater are soilid liquid gas plasma.

A physical change is sudstance change but the substance always remains the same.A chemical change is the idenity of a sub stance changes.The 4 sstates of matter are solid,liquid,gas,and plasma.

The difference between chemical change and physical change. Chemical change is when you put powder in water you can't seperate the two. But a phisical change iswhen you can mix things together and take them apart.The 4 states of matter are solid ,liquid , gas, and plasma.

A physical change means it is still the substance it was before you did something to it like if you melt butter it is still butter. A chemical change is when the substance is different like if something changes color you can't change it back. The four states of matter are solid, liquid, gas, and plasma.

The 4 states of matter are solid, liquid, gas,and plasma. the difference between chemical change and physical change is chemical can be changed and can't be changed back. phycical can be changed back.

A chemical change is when you mix two things together and you can't take the substances apart again. A physical change is when you mix two things together and still can undo the things and tell what they are.The 4 states of matter are plasma, gas, liquid, and solid.
