A physical change alters a given material without changing its chemical_____?
The answer is physical change.
As in ice melting to water, or a liquid vaporizing.
Yes, a physical change alters a given material without changing its chemical.
...The question is a fill in the blank type question, it's supposed to read:
"A physical change alters a given material without changing its chemical _________?"
Yes, a physical change doesn't affect the chemical composition of the molecule.
Yes- ice can melt for example.
Appearance
yes
its no
there is to types of change to a substance chemical and physical in a physical change the result is a mixture also most times you can change your end result into what you started with e.g.freeze-melt evaporate-condesate
Nothing does, because there is no such thing as "an unbalanced force",so that scenario can never occur.When an unbalanced group of forces acts on an object, the speed or directionof the object's motion can change, but its mass does not change.The mass of the object.
melting is a physical change. freezing is also a physical change. the only thing that changed was the state of matter. a chemical change for example is buring, the substance changes to co2 and h2o.
A new substance is formed only after a chemical change.
Freezing point is a physical property. It is the temperature at which a substance changes from a liquid to a solid state under standard atmospheric pressure. Physical changes involve a change in state without altering the chemical composition of a substance.
A physical change is when a substance changes, but still keeps its identity. When a chemical change occurs, the substance changes its identity.
The term for a process that does not change the identity of a substance is a physical change. This type of change alters the appearance or state of a substance without changing its chemical composition.
Appearance
No, a physical property DOES NOT change the identity of a substance. That would be a chemical property which DOES change the identity.
If form changes but identity doesn't change then it is a physical change.
Changes of the matter that do not change the composition of the substance.
Of course not. It is a physical change. A chemical change occurs when the identity of a substance changes.
No breaking a plate is a physical change. A chemical change is a change to a substance where its identity changes. When you break a plate you still have a plate not a new substance.
Mowing the lawn is a physical change. Cutting your hair isn't a chemical change, it's still hair, and it will grow back :) Chemical changes alter the identity of a substance, whereas physical changes do not.
chemical- changes identity of substance. some signs: bubbles, precipitate forms, color change, difference in temperature physical- does not change identity of substance. can be homogeneous or heterogeneous. meaning appearing to be the same throughout and appearing to have different parts throughout; respectively.
cooking an apple is causing a physical change because in a physical change, the IDENTITY of the substance never changes. (identity=atomic makeup. in a chemical change, the IDENTITY does change, due to a chemical reaction. because there is no change in the identity of the apple, baking it is a physical change
The ease of corrosion of resistance to corrosion is a chemical property and not a physical one. Corrosion is a chemical change which changes the identity of the substance.
