Is a rusting bicycle a physical or chemical change?
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.
If chemical energy can be used to produce kinetic energy what is an example of using chemical energy to produce kinetic energy?
Your car.
Does volume change when substance changes states?
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.
Real life example of chemical weathering?
The main agents of chemical weathering are acid precipatation, lichens, and other plants like mold decaying the rock. :)
A construction truck collides with the back of a subcompact car Which one has the larger change of velocity during the collision?
The smaller vehicle will encounter the larger velocity change.
Is the action of saltwaterand air on car fenders and panels chemical or mechanical?
It's a chemical reaction
Would the action of water salt and air on car fenders be mechanical and chemical weathering?
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.
A chemical change is a change in what?
it is ge in the substance that you have. say if you have a car and it has rust that is a chemical change
Is petrol used in a car engine a chemical change?
yes it is a chemical change
Is car exhaust fumes mixing with water a chemical change?
It is a chemical change.
When carbon dioxide comes from the fuel of the car is it a physical or chemical change?
chemical change
Is a inflation of a car tire a chemical change?
No. Nothing changes in its chemical nature.
Is crashing a car chemical change?
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.
Is a car rusting a chemical change or a physical change?
A car Rusting is a chemicall change as a the iron in the car is converted into a different substance: iron oxide.
Is a car battery discharging a chemical change?
no
Is a car crashing a physical or chemical change?
The key here is what happens to the matter. Does it change into a different material or just change shape? If the metal changes into a new substance like iron into rust then it would be chemical but this is definitely a physical change. - - - - - Car crashes can cause both physical and chemical changes. The bending of the car is a physical change, but if the wreck catches fire that's a chemical change.
Is charging of car battery chemical change?
Yes. The charging causes a chemical change in the electrolyte of the battery.
