What change occurs that alters the appearance of matter?
physical change
What characteristics best describe what happen during a physical change?
The compsitions stays the same :0
Is it true that a change that alters the form or appearance of matter but does not make any substance in the matter into a different substance is called a chemical change?
Nope. That is a physical change. If I crush a cookie into powder, it is still cookie- no chemical change. The form and appearance have changed. But pour powdered cookie onto your tongue, and it is still cookie.
How are states of matter and physical properties the same?
A solid matter has a solid appearance, a gaseous matter has a gaseous appearance, and a liquid matter has a liquid appearance.
True or false Nuclear reactions convert matter into energy?
False.Atoms themselves only change during nuclear decay, fusion or fission. Outer electrons can be shared, donated or received during bonding but the atom doesn't change in and of itself.When matter changes state the bonds themselves are not affected. All that happens in a change of state is that molecules gain more kinetic energy. The bonds within the molecules are not altered.
A change in appearance of matter without actually changing the matter itself?
Chemical change
What change occurs that alters the appearance of matter?
physical change
Is it possible to create matter or only change pre-existing matter?
Matter can not be created nor destroyed, only altered.
Physical Change?
Changes of the matter that do not change the composition of the substance.

Which change takes place during the boiling of water?
Boiling water is an example of a physical change because the water being boiled is only changing its state of matter (solid, liquid, gas, plasma), its identity is not being altered since after boiling the water, it is still water. However, some changes are harder to tell. Cooking, for example, is a chemical change because it is more than the physical appearance(s) that is/are being altered through the action despite reference being the same. Chicken is chicken and frying a chicken does not change the fact that it is a chicken but it is no longer just chicken as changes have occurred beyond the physical.

What happens to the particles of matter during a chemical change?
it will change to liquid
How does the start of matter change during evaporation?
If you mean the "state" of matter, during evaporation, it changes from a liquid to a gas.
