What is the differnce between physical and chemical change?
Physical changes are changes in appearance, state, or form of matter without altering its chemical composition. Chemical changes involve the formation of new substances with different chemical properties. Examples of physical changes include melting ice or tearing paper, while examples of chemical changes include rusting of iron or burning wood.
Are changes in the state of matter are physical chemical or neither?
Changes in the state of matter are physical because they involve a change in the physical properties of a substance, such as its shape, volume, or density, without altering its chemical composition. Examples include melting, freezing, evaporation, and condensation.
Zinc has a hardness on the Mohs scale of 2.5 and a density of 7.13 at 25 is it physical or chemical change?
The hardness and density of zinc are physical properties, as they do not involve any change in the chemical composition of the substance. Changes in physical properties can be observed without altering the chemical identity of the material.
Chemical changes can be reserved by physical change?
No, chemical changes cannot be reversed by physical changes. Chemical changes involve the formation of new substances with different properties, while physical changes only affect the state or appearance of a substance without changing its chemical composition. Once a chemical change occurs, it cannot be undone by a physical change.
Which of the following are chemical properties changes temperature ripening evaporation humidity?
Temperature, evaporation, and humidity are physical properties, while ripening is a chemical property. Chemical properties involve changes in the chemical composition of a substance, while physical properties relate to characteristics such as state, appearance, and behavior under certain conditions.
Changes in properties of matter are called?
physical or chemical changes
What are physical and chemical?
physical changes do not change the chemical properties of a substance
Does a chemical reaction change physical properties or chemical?
A chemical reaction changes the chemical properties of substances involved by forming new substances with different chemical compositions. This can result in changes in physical properties such as color, temperature, odor, and state of matter.
Is melting ice a chemical or physical change explain?
It is a physical change because when you have a chemical change it changes the properties and makes it into a new thing, and it can't be reversed. Physical changes are usually just changes of states (solid, liquid, gas) and a physical change can be reversed.
What are property changes?
the properties that change are physical and chemical properties!!! :)
Can matter undergo changes in both its physical and its chemical properties?
Yes, matter can undergo changes in both its physical and chemical properties. Physical properties changes do not alter the composition of the substance, such as changing state from solid to liquid. Chemical properties changes involve a chemical reaction that results in the formation of new substances with different chemical compositions.
Difference between chemical and physical change?
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
What is the diffence between physical and chemical properties as well an physical and chemical changes?
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
What is the difference between a chemical change and physical change?
A physical change changes the physical properties of an element like color where chemical changes change the chemical properties of an element and usually can't be undone.
Do chemical changes affect the chemical structure of a substance?
Yes, chemical changes result in a change in the chemical structure of a substance. During a chemical change, new substances with different chemical compositions are formed through the rearrangement of atoms and bonds. This is in contrast to physical changes, where the chemical structure remains the same even though the physical properties may change.
Are color and density chemical changes?
Color and density are physical properties, not changes.
How can you tell that melting boiling dissolving are physical changes?
The physical and chemical properties, and chemical composition, are not changed after a physical change.
