Is it true that if a physical change that occurs when a substance changes composition by forming one or more new substances?
No. That is a chemical change. In a physical change, their is no change in chemical composition forming one or more new substances.
Is breaking a pencil in half a chemical change?
Nope - it's a physical change. The chemical composition of the pencil is still the same !
Is breaking of glass physical or chemical change?
It is a physical change. The resulting fragments of glass are still glass and of the same composition.
Is a glass breaking chemical or physical?
It is a chemical change. It keeps its same chemical composition and is in a reversible state. You can remelt it and once again, make glass.
Does breaking a mirror cause a change of chemical properties?
Breaking a mirror does not cause a change in the chemical properties of the mirror itself. The act of breaking the mirror may result in physical changes, such as the mirror's fragments having sharp edges, but the chemical composition of the mirror remains the same. Mirrors are typically made of a layer of reflective material, like silver or aluminum, which is deposited on the glass surface, and breaking the mirror does not alter this composition.
Is breaking glass chemical or physical?
Breaking glass is a physical change, as it does not change the chemical composition of the material.
Is it true that if a physical change that occurs when a substance changes composition by forming one or more new substances?
No. That is a chemical change. In a physical change, their is no change in chemical composition forming one or more new substances.
Are icicles forming on the edge of the roof of physical or chemical change?
No it is not. The chemical composition is H2O before and after freezing.
The breaking up of rocks of the earth without causing a change in their chemical composition is?
chemical weathering
Is breaking a pencil in half a chemical change?
Nope - it's a physical change. The chemical composition of the pencil is still the same !
Is breaking glass a physical change and why?
It is a physical change because the chemical composition remain unchanged.
Is breaking a mirror an action with new chemical properties?
No. After breaking the mirror, the chemical properties of the remaining pieces are the same as the intact mirror. This is a physical change, not a chemical change.
Is clouds forming in the sky a chemical or physical change?
Original answer is INCORRECT. Clouds forming in the sky is a physical change because a chemical change requires a change in the chemical composition of a material and the H2O, no matter a solid liquid or gas, is always H20.
When glass brakes is it a physical change?
A glass breaking is a physical change because the chemical composition of the glass does not change.
Is breaking of glass physical or chemical change?
It is a physical change. The resulting fragments of glass are still glass and of the same composition.
Is breaking a glass beaker chemical or physical?
Breaking, grinding, cracking are all examples of a physical change. The nature of the substance has not changed, just the size of the pieces has changed.
Is a glass breaking chemical or physical?
It is a chemical change. It keeps its same chemical composition and is in a reversible state. You can remelt it and once again, make glass.
