Is copper in a Bunsen burner a physical or chemical change?
Using a Bunsen burner to heat copper is a physical change. The copper undergoes a change in its physical state from solid to liquid without changing its chemical composition.
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.
Is lightning flashing across the sky a chemical or physical change?
Lightning flashing across the sky is a physical change. It results from the movement of electrical charges in the atmosphere, without any changes in the chemical composition of the air or the resulting light.
Is heating sodium chloride with a Bunsen burner a chemical change?
No. It is a physical change. It only melts.
Is when a burner gets red hot an example of a chemical change?
This is indeed a physical change. There is a colour change, but if the substance is cooled down it is still the same. All that providing electricity is really doing is adding Energy to the burner.
Classify the following as a chemical or physical property or change. A tree is struck by lightning. why?
The tree being struck by lightning is a chemical change because it involves a transfer of energy that can cause chemical reactions in the tree, such as burning or decomposition. This changes the tree's composition and cannot be easily reversed.
Why the lightning of bulb not a chemical change?
The lightning of a bulb is a physical change because the transformation is reversible - the electricity passing through the filament causes it to heat up and emit light, but the filament itself remains the same material. A chemical change, on the other hand, involves a change in the chemical composition of the substance, which does not occur in this case.
Is stapling an envelope a physical change or chemical?
A physical change
Is painting a door a physical or chemical change?
Physical change of the paint, not the door.
Is thunder a physical or chemical change?
Thunder is a physical phenomenon that occurs when lightning heats the air rapidly, causing it to expand and create a shockwave. It is not a chemical change because the composition of the air molecules remains the same before and after the thunder occurs.
