Does a phsical change or chemical change affect the matter in an object?
A physical change is reversible and does not affect the composition of a substance. On the other hand, chemical change is irreversible and permanent. A substance undergoing a chemical change forms a new substance which has different composition than the original substance.
Is mowing the law a physical or chemical change?
Mowing the lawn is a physical change because it involves cutting the grass without altering its chemical composition. The grass remains the same substance; it is simply reduced in height. Physical changes affect the form or appearance of a material, while chemical changes involve a transformation into a different substance.
Differences between physical changes and chemical changes?
Physical changes are changes that affect the form of a chemical substance, such as changes in state or shape, without changing its chemical composition. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are often irreversible.
Is a carton of milk going sour a physical or chemical change?
A carton of milk going sour is a chemical change. This process involves the growth of bacteria that produce lactic acid, altering the milk's composition and resulting in changes to its taste, smell, and texture. Unlike physical changes, which do not affect the chemical structure of a substance, souring milk irrevocably transforms it into a different substance.
What effect does an energy change have on the identity of a substance?
The identity of the substance reamain unchanged.
What changes with a chemical change?
chemical changes affect the chemical properties as well as composition of matter , that result in the formation of a new substance.
Does a phsical change or chemical change affect the matter in an object?
A physical change is reversible and does not affect the composition of a substance. On the other hand, chemical change is irreversible and permanent. A substance undergoing a chemical change forms a new substance which has different composition than the original substance.
When gold changes from a solid to a liquid is that a physical or chemical change?
The change from a solid to a liquid is a physical change, as the substance's chemical composition remains the same. Physical changes affect the state or form of matter without altering its chemical composition.
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.
What is one major difference in a physical change and a chemical change is?
Physical change, changes the appearance or the surface. Chemical change, changes the minerals inside the object. Physical deals with the appearance and the surface. Chemical changes the structure of the minerals inside the object.
How does a chemical change affect the composition of matter?
chemical change = chemical reaction. ( the composition of matter always changes). In a chemical change the matter in one thing changes, for example you will know a chemical change has occurred when the color or odor has changes or when a new gas is given off.
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.
What are phyisical changes?
Physical changes refer to alterations that affect the appearance or state of a substance without changing its chemical composition. Examples include changes in shape, size, color, or state (solid, liquid, gas). These changes are usually reversible and do not involve the formation of new substances.
Differences between physical changes and chemical changes?
Physical changes are changes that affect the form of a chemical substance, such as changes in state or shape, without changing its chemical composition. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are often irreversible.
How is an chemical change differs from a physical change?
Physical change is the change in which only physical properties changes ,like color, hardness, density etc. Chemical changes affect the composition as well as chemical properties of matter and result in formation of new substance. Examples of chemical changes are : Burning of coal Burning of Paper Electrolysis of water
What effect does an energy change have on the identity of a substance?
The identity of the substance reamain unchanged.
A chemical change differs from a physical change because in a chemical change a substance?
undergoes a chemical reaction, resulting in the formation of new substances with different chemical properties. This usually involves a rearrangement of atoms and the breaking and forming of chemical bonds, leading to a change in the composition and structure of the material. In contrast, physical changes only affect the physical state or appearance of a substance without altering its chemical composition.
