Flat tires is a sign of physical change. The tires go from being normal, to then being flat. This changes their physical form.
Flat bicycle tires are typically a sign of air leakage, often caused by punctures, valve issues, or damage to the tire itself. Riding on flat tires can lead to further damage to the tires and wheels, making it important to address the issue promptly. Regularly checking tire pressure and inspecting for wear can help prevent flats. Maintaining properly inflated tires enhances performance, safety, and extends the life of the tires.

Yes, a glowing neon sign represents a physical change because the neon gas inside the sign undergoes a change in energy state to emit light. This change is reversible and does not alter the chemical composition of the neon gas.
No, evaporation causes a change in the state of matter (liquid to solid) which is a physical change
Chemical Change Only
It's not a physical change. Rather, it is a sign of an already completed chemical reaction.
No, evaporation is a physical change and not a sign of a chemical change. Evaporation involves the change of a substance from a liquid to a gas without altering its chemical composition.
After a physical change the molecule remain intact.After a chemical change the molecule is modified.
- Color is a physical property and the change of color also.- Color change may be a sign of a chemical reaction.
second space with flat sign. or high a flat is line above fifth line with flat sign
It is a chemical change because it leaves a residue (which is a sign of chemical change) Hope that helps
