Is lightning a chemical or physical change?
Lightning is a physical change. It results from the movement of charged particles in the atmosphere, causing a visible electrical discharge. This process does not involve any change in the composition of the substances involved, making it a physical change.
What is edible in physical change?
A physical change is a change where the atoms might get separated but there is no change in it's chemical. It all depends on what you did with the atoms (For example, poisoning something is a physical change), and if the thing itself is edible.
Is scrubbing the floor a physical or chemical change?
Scrubbing the floor is a physical change because the appearance or state of the floor is altered without changing the chemical composition of the materials involved.
Is ice melting at 0 degrees Celsius a chemical property?
No, the process of ice melting at 0 degrees Celsius is a physical change, not a chemical property. It involves a phase change from a solid to a liquid state without any change in the chemical composition of the ice.
Is a piece of copper cut in half a physical or chemical change?
Cutting a piece of copper in half is a physical change because it only alters the physical appearance of the copper without changing its chemical composition.
Is decomposing sugar a physical change?
This reaction is a chemical process.
What does physical change does not involve?
A physical change does not involve a change in the chemical composition or nature of the substance. It only affects the physical properties, such as shape, size, or state of matter.
Is decomposing water physical or chemical change?
Chemical change; bonds are broken when water decomposes into hydrogen and oxygen.
Is the decomposing of a solution physical or chemical?
The decomposing of a solution can be either physical or chemical, depending on the nature of the process. Physical decomposition involves a change in appearance or phase without altering the chemical composition of the solution. Chemical decomposition, on the other hand, involves a breaking down of the chemical bonds in the solute molecules, resulting in the formation of different substances.
What is a physical change cooking egg decomposing meat burning gasoline or rusting iron?
in fact all are chemical changes.
What is the difference between boiling water and decomposing water?
Boiling water is the process in which water reaches its boiling point and turns into vapor, while decomposing water involves breaking down water molecules (H2O) into its constituent elements, hydrogen and oxygen. Boiling water is a physical change, while decomposing water is a chemical change. Boiling water is reversible, while decomposing water is typically irreversible.
Is pop fizzing a physical change?
Both. The chemical change is H2CO3 decomposing into H2O and CO2. The physical change is the dissolved CO2 forming a bubble and "fizzing" up to the surface.
Is hydrogen peroxide decomposing a physical or chemical?
This is a chemical process.
Is heat on cupric carbonate a chemical or physical change?
It depends on how much heat is added; for instance: Chemical change indicates a change in the chemical formula. Heating it would eventually decompose it, so it is a chemical change if you are decomposing it. A change in phase (solid-->gas) would be a physical change, so as long as the chemical formula stays the same, meaning it doesn't react with anything in the air or decompose, it would be a physical change
Is decomposing a chemical or physical change?
Decomposition of any compound e.g. when heated CaCO3 compound decomposes to CaO and CO2 compounds, gives different substances and hence a chemical change. Y.Ozkalay
Is decomposing water by passing an electric current through it a chemical or physical change?
Decomposing water by passing an electric current through it is a chemical change because it involves the breaking of the chemical bonds in water molecules (H2O) to form hydrogen gas (H2) and oxygen gas (O2). This reaction results in the formation of new substances with different chemical properties.
Is hydrogen burning a physical or chemical change?
The burning of hydrogen is a chemical change because it involves the rearrangement of the atoms in the hydrogen molecule to form water. This process also releases energy in the form of heat and light.
