Chemical change
No. Nothing changes in its chemical nature.
No, pumping up a tire is a physical change because it does not alter the chemical composition of the tire or the air inside it. The process simply involves adding or removing air, which is a reversible change.
When a car tire is inflated, the air particles inside the tire collide with the walls of the tire and with each other, creating a force that exerts pressure on the walls of the tire. The pressure builds up as more air is pumped into the tire until it reaches a point where it is equal to the atmospheric pressure pushing back on the tire.
because of the pressure. when you add more air to the tyre, or inner tube, the air inside squashes together, which makes the tyre hard. the pressure is measured is PSI, or pounds per square inch. a fully inflated mountain bike tyre should be around 40 psi. hope this helps
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 inflation of a tire is considered a physical property, as it relates to the tire's volume and pressure. It is not a chemical change, as the composition of the tire material remains the same.
physical
physical change. the rubber is still rubber and the air is still air, so NO chemical change has occured
Chemical change
Yes, a flat tire is considered a physical change because the rubber material in the tire is simply being compressed and there is no change in the chemical composition of the rubber.
No. Nothing changes in its chemical nature.
No, inflating a bike tire is a physical change because it does not change the chemical composition of the tire or the air being pumped into it. When air is added to the tire, it simply increases in volume and pressure without altering its chemical properties.
When a tire is properly inflated it will be level to the ground. Over inflated and the middle of the tire has the most pressure on the ground. Under inflated and the sides of the tire have the most pressure on the ground.
The same as a tire that has not been inflated.
No, a tire losing air is a physical phenomenon caused by air molecules escaping through tiny holes or leaks in the tire. This is not a chemical reaction because it does not involve a change in the chemical composition of the tire or the air.
Yes it is a physical change
