Why is a crashing car a physical change?
A crashing car is a physical change because the collision alters the car's shape and form, but the chemical composition of the materials remains the same. No new substances are produced as a result of the crash, so it is considered a physical change.
Why is frost on a car window a physical change?
Frost forming on a car window is a physical change because it is a reversible process where water vapor in the air solidifies into ice crystals when it comes into contact with the cold surface of the window. The chemical composition of the water molecules remains the same before and after the frost forms.
What physical quantities discussed in this chapter change most when a junked car is neatly crushed into a compact cube?
Some of the physical quantities that change the most when a junked car is crushed into a compact cube include volume, density, and structural stability. The volume of the car decreases significantly as it is crushed, leading to a much higher density in the compact cube. The structural integrity of the car is also altered, with the transformation from a complex shape to a simple cube impacting its stability and strength.
When a car stop why are you tending to move forward?
It is due to inertiaInertia is the resistance of any physical object to a change in its state of motion or rest, or the tendency of an object to resist any change in its motion.
If a car was crushed into a cube which would change mass or volume and why?
It would only change the volume. This is because volume is how much room an object takes up, and crushing the car will make volume smaller. Mass is how much "stuff" an object is made of. So unless like, the bumper falls of, mass stays the same.
Rust on a car is the result of a chemical change because the rusting process does what?
It forms a new substance.
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 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.
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 washing a car a physical change?
yes
A car battery runs down a physical change or chemical change?
i tink that it is a physical change
What are the Physical and chemical changes as a car ages?
Physical changes in an aging car may include rust formation, paint fading, and wear and tear on the interior. Chemical changes can result from exposure to environmental factors like air pollutants leading to corrosion of metal parts, degradation of rubber components, and breakdown of fluids such as engine oil. These changes can impact the car's performance and appearance over time.
Why is smashing a car a physical change?
Smashing a car is a physical change because when the car is smashed it's, still the car. You didn't use any chemiclas to change it - the changes are only in appearance. So it's still a car until you use some kind of chemical to change it.
As a car gets older will its compression ratio change?
Yes, as a car gets older its compression ratio will change. This is because the rings within the car will gradually age and rust.
Is breaking and antacid tablet you physical or chemical change?
This change is a physical change because the matter is made up of the same components that it consisted of before it was broken. An example of a chemical change is the molecular rearrangement of matter like rust on a car.
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.
Is car rusting physical change?
No, a car rusting is a chemical change because a new substance is formed. Iron will react with oxygen (found in water) forming iron oxide. The product, iron oxide, has different properties from both iron and oxygen. A "chemical change" describes any reaction where a new substance is formed. However, if a substance just changes forms, it is a physical change. For example, water freezing is a physical change.
