It's a physical change. You can, theoretically, turn a car fender back into a flat sheet of steel. You wouldn't want to, and the machine you'd need to do it would be immense, but you could.
Ah, what a lovely question. When a bicycle rusts, it's actually a chemical change taking place. The metal is reacting with oxygen and moisture in the air, creating a new substance called iron oxide. It's all part of nature's way of transforming things, just like how we transform a blank canvas into a beautiful painting.
Your car.
Yes. Usually when a substance freezes, or becomes a solid, it will decrease in volume, causing an increase in density. Water is an exception, which is less dense when it freezes/becomes solid.
The main agents of chemical weathering are acid precipatation, lichens, and other plants like mold decaying the rock. :)
The smaller vehicle will encounter the larger velocity change.
It's a chemical reaction
Yes, the action of water, salt, and air on car fenders would primarily be classified as chemical weathering. Water and salt can cause oxidation and corrosion on the metal surface of the fender, while exposure to air can facilitate these chemical reactions. Over time, this chemical weathering can lead to rust and deterioration of the fender.
it is ge in the substance that you have. say if you have a car and it has rust that is a chemical change
yes it is a chemical change
It is a chemical change.
chemical change
No. Nothing changes in its chemical nature.
no
No, crashing a car is a physical change. A chemical change involves the rearrangement of atoms to form new substances, while crashing a car simply changes the physical shape and structure of the material without altering its chemical composition.
A car Rusting is a chemicall change as a the iron in the car is converted into a different substance: iron oxide.
Yes. The charging causes a chemical change in the electrolyte of the battery.
The velocity of a car can change by increasing its speed, such as accelerating when pressing the gas pedal, or by decreasing its speed, such as decelerating when applying the brakes.
