The internal pressure increase in the tire.
physical change. the rubber is still rubber and the air is still air, so NO chemical change has occured
physical change.. cooler air in the tire becomes denser, lowering overall pressure. The chemistry of the air in the tire does not change.
no. no chemical changes occur. air just moves from the inside of a tire to the atmosphere
yes am serious.that is why am asking what are chemical ingredient to make tire black wax.
Inflating a tire with air is a physical change because it is not changing the tire chemically. It is only changing the physical appearance of the tire.
The internal pressure increase in the tire.

no its a physical change
It takes very little skill or effort to change a bike tire. Anyone who rides a bike should be able to do it.
Pretty much the same way you change any other bicycle tire. I'll post a link that tells you how.
reversible
hump it
Chemical change
pull the outer part of the tire off pull off the deflated bike tube replace it with a new bike tube put the outer part of the tire on
physical change. the rubber is still rubber and the air is still air, so NO chemical change has occured
To be aware of what air pressure you are inflating it to after the repair.
